MYHockey General Info

MYHockey was developed to share the love of youth hockey with others. It started as a project to share links to other associations and leagues with others. It progressed to teams as my son's team sought competition outside our immediate geographical area. When we started looking at teams, we began to look at records to see if another team might be good competition for my son's team. We quickly realized that a team's record was not an indicator of strength and then we started to wonder who (which team) was really better and by how much. As our team pursued a search for good competition, we made some mistakes that left both us and our opponents less than satisfied after a weekend of blowouts. Over time, MYHockey emerged as a tool to help youth hockey fans, coaches and managers learn more about the sport we all love.

MYHockey's ratings are computed mathematically, with no subjective weighting or human determined values. MYHockey rates teams based upon how well they play against other teams and how good those teams are. These two factors are "AGD" or "average goal differential" and "SCHED" or "strength of schedule". AGD is currently calculated by accumulating the goal differential of each game, to a maximum of 7, and divides it by the number of games played. Using a max game goal differential of 7 does "penalize" teams that blow out opponents, but this is common in rating systems as it takes away the incentive for teams to run up scores and allows them to have a bad game by capping the mathematical damage. The strength of schedule is computed by averaging the rating of each game opponent. AGD and SCHED are added together to compute a team's rating.

There is no preferential treatment for teams from certain leagues. All teams are assumed to be equal and having a rating of zero before the system mathematically calculates your SCHED and AGD based entirely upon game performance. A team's SCHED is not only determined by the teams it plays, but by the teams its opponents play and its opponents' opponents play, etc. All teams in a given age level (i.e. Midgets) are ranked in one statistical pool. The math does not know if the teams are major, minor, AAA or AA, it simply computes based upon who a team has played (SCHED) and how well they have done (AGD).

In general, as teams start getting 20+ games under their belts, the system tends to be very accurate. There are, however, some occasional exceptions.

If a group of teams (i.e. a league) doesn't play others outside its group, their placement relative to all other teams cannot be accurately determined, but relative to one another it is accurate. Groups of teams with limited outside play can be inaccurately skewed by the scores of only a few games, which might not be representative of the group's overall ability. Accuracy significantly increases with more games and more interplay and it makes sense for there to be a minimum number of games before teams are ranked.

Assuming teams have all played enough games against both league and non-league teams, inaccuracies may still exist. Some teams play differently (a lot differently) depending upon which goalie is in net for a specific game. In this case, the ratings average out the play and may not completely reflect either scenario. Missing players, home vs. away, double rostered players are a few other scenarios that could influence the accuracy of the ratings. It's not an exact science. The ratings should be used to determine what teams might be good non-league opponents and which bracket of a tournament may be more appropriate. They are not meant to be the AP Poll for youth hockey.

There are a couple weaknesses to the current system. The first deficiency is with teams that emphasize development in some games. They are "penalized". That same team may then focus on winning big tournaments and succeed, but may never achieve the rating that they "deserve". Secondly, teams that "come on" in the second half of the season are "penalized" by early poor performances. All games throughout the season count equally and that may not reflect a teams performance near the end of the season.

Yes, it seems wrong, but a team that you have a winning record against can be ranked ahead of you. It's all in mathematics. It depends on who else your team has played and how well you did as well as who the other team has played and how well they did. In a season of games, there will be some anomalies.

Your rating can go down even though your team wins. This can happen for a couple different reasons. First, if your team is rated 3.0 points (1 point = 1 goal) better than your opponent and you win two close games by 1 goal each, your average goal differential (AGD) is +1.0 against a team that it was expected to be +3.0. This would likely have a negative impact on your rating. Another scenario has you doing as expected against your opponent, but a large percentage of the teams you played earlier in the season doing unexpectedly bad. This lowers your strength of schedule and would lower your team's rating. It is almost impossible to guess how much and in what direction your rating will move each week because of the complexity of the math.

Two additional notes. During the entire season, new teams continue to be added to the system. Teams rated in the middle of the pack in October may fall 100 spots by the end of the season while improving, simply because the number of teams added to MYHockey increases over time. It might be best to compare your team to others in your league or geographic area and see if your rating improves relative to theirs. Also, MYHockey now has available a page that explains the mathematics behind the rating. From either the scores page for a particular team or from the team information page, you can find a link to the math page.

Everything is relative. The number specifically means nothing, but might be used to understand the relative competitiveness of two different teams. A 1.0 point differential equates to a theoretical goal 1.0 goal advantage by the team with the higher point value. Squirts, Peewees, Bantams, Midgets/Prep/HS, Juniors and College are all calculated separately. While a Peewee Minor AAA team can get a pretty good sense on how good they would fair against a Peewee Major AA team because all Peewee ratings are calculated relative to one another, one cannot compare a Squirt Major AAA team to a Peewee Minor AA team in the same fashion. MYHockey has some limitations and figuring the relative difference between stronger squirt teams and weaker peewee teams is one of them.

"Record" is represented by wins-loses-ties. As described above, the "Rating" is simply the sum of the "AGD" and "SCHED". "AGD" is average goal differential. This can be a positive or negative number that equals goals for (GF) minus goals against (GA) divided by games played (GP). One caveat, the system currently has a maximum goal differential of six (7) for any single game played. This means that if a team plays a number of games decided by more than seven goals, it's not quite as simple as GF-GA/GP. "SCHED" is the average strength of schedule of all opponents. Fundamentally you can add the "RATING" for all opponents and divide by GP. "Details" will give you more information about the team while "Scores" is a link to a team's complete set of season game scores as recorded in MYHockey.

A couple hints to give you the full power of MYHockey. Any teams with known team websites will be represented by underline/hotlinked team names. Clicking on the team name will open an additional window to this team's web site. When viewing scores, each opponent's schedule is just a click away. For example, if you are viewing the game scores of Team X and they played Team Y, you can view Team Y's game scores by simply clicking on Team Y's name.

Teams are displayed on the rankings only after having played at least five games against other teams in the system. Games not recorded via publically accessible team, league and tournament web sites are unlikely to be recorded (there is no magic here).

MYHockey has now expanded to include most "A", "AA" and "AAA" youth hockey teams in the US and Ontario. We continue to build out missing areas in other parts of Canada. At this time, we do not have the resources to cover "B" or lower levels of travel hockey. If you are interested in helping maintain "A" or higher level travel hockey and cannot find your teams in MYHockey, please contact us with details and we'll try to get any missing leagues and teams into the system.

Missing scores are typically not in the system for one of a few different reasons. First, divisions of leagues that MYHockey considers or which are labeled as "B" level travel are not eligible for MYHockey and games against these teams will not be entered into MYHockey. Second, game scores found on league and team web sites are the primary source of MYHockey volunteers and if the game score is not located on a web site where someone is looking, it will not get entered into the system. Third, game scores against ambiguous teams (i.e. "Flames" or "Chicago Blues" or "Columbus") will not get recorded unless the exact team can be identified. Spell out team names and levels more clearly so there is no question in the mind of our volunteers. Lastly, some scores are not entered or entered in a timely fashion because there is no volunteer covering their league/division. Please consider volunteering or becoming a member. To find out more, go to the Report Scores Page.

MYHockey members can now request that games against teams of a different age level or games against ineligible teams be added to the system so that their game schedule can be 100% complete. If these things are of interest to you, please consider a membership.

Games played by teams of different age levels (i.e. peewee vs. bantam) cannot be used to calculate a team's rating/ranking. There has traditionally been no reason to enter these games into MYHockey. Many members, however, have requested an ability to enter all of their game scores into the system. As such, MYHockey does allow games by teams of different age levels to be entered into the system by members, but this is not an option for those using the guest online entry form.

Games played by girls teams versus boys teams are essentially the same as games played by teams of different age levels. These games cannot be used to calculate a team's rating/ranking. These games can only be entered into the system by members adn are not an option for those using the guest online entry form.

MYHockey now includes Squirt Minor through Midget Major teams throughout the US & Ontario at A, AA and AAA levels. Teams playing in "B" level leagues are not included at this time. Virtually all Canadian Midget and Bantam AAA teams are in the system, in addition to the majority of the Peewee AAA teams, where Peewee AAA is played. Additionally, MYHockey is expanding to cover the "AA" levels of hockey throughout Canada. If you see something that is missing and are willing to help, please let us know. Girls teams from peewee through Midget/College are now included. All USA High School hockey, Juniors, and College hockey are now available. Their Canadian counterparts are also continuing to be built out. What is not included? Mites (or Novice as you Canadians refer to them). Summer Hockey teams are not included. Junior programs running outside the Canadian and US sanctioning bodies are not included at this time. Still not seeing what you are looking for? Send MYHockey an email. Growth is and has been a specific result of user interest.

Next to every score in the database is a red check mark in the "Fix" column. If a score is incorrect, click on the corresponding check mark to request that it be fixed. Please provide documentation (website that has the correct score posted is preferable) and tell us specifically how to fix the score. If the score is a duplicate, especially an incorrect duplicate, make sure you request that we delete the duplicate score.

Again, mistakes are inevitable. If duplicate scores have been posted, complete an online score correction request to get things corrected. We try to catch these ourselves, but we appreciate your help. To resolve the issue of missing game scores, please visit the Report Scores page for more information on volunteering and/or reporting these scores.

MYHockey is working on making all information correctable via an online form, but association information has not yet been completed. You will see a pencil icon just to the right of association information when the online correction form has been implemented. Until then, use the contact information found on the Contact Info page.

Absolutely. MYHockey has actually helped leagues who have pre-season schedules to help determine who plays in which division during the regular season. This service is available to others as well upon request. Please use the Contact Info page to reach us and begin discussing your needs.

Accurately post all league scores! The number one thing a league can do is post, on the internet in a timely fashion, all league game scores. Encouraging associations/teams to create team web sites and make non-league game scores available to the public would also help.

Create a team web site and list all game scores in an area where our volunteers can easily find it. Also, please clearly identify your opponents. Ambiguity means we cannot post the results, even if you have them on your web site.

Volunteer to enter scores. Become a member. Keep us honest by reporting any errors.

MYHockey is free just as Google is free. Advertising covers most of the cost of running the website. Volunteers, from the founder to the quiet goalie's mom on your team, contribute countless hours with a common goal in mind. MYHockey's mission is to provide you the best, most complete and accurate information about youth hockey. Memberships are available at a very low price for those wanting extra features and/or who would like to provide financial support for the site.

No! Everything that was available for free previously is still be available for free. However, you can now choose to join MYHockey for a small fee to obtain additional services that have been requested by our users. This is very similiar to how Google and the Wall Street Journal provide services. Basic content is free, premium content is available for a small fee. It is optional and available to those who want to support this website.

MYHockey Site Rules

MYHockey typically starts the season around August 20th. There are a few leagues in the US that have permission from USA Hockey to start the fall season in late August. As a result, the system turns live, typically on a Friday about two weekends before the US Labor Day holiday. This creates a number of issues. Most Ontario teams are still using summer rosters until August 1st. There is some deception going on with Ontario AAA teams and tournaments in late August, where many will play games with winter rosters, but claim they were summer rosters so they don't get in trouble. Bottom line is that most of these games will not be recorded in the system. As stated in the MYHockey Game Definition Rules, anyone can request that an August game be removed and it will be. Most simply should not be in the system. Come September 1st, everything changes and it takes a lot of effort for a game to be removed or be considered invalid. We like for everything that looks like a game to be entered into the system. There are a few exceptions as highlighted in the MYHockey Game Definition Rules. The season ends either on March 31st or when post-season play ends for a given team. USA Hockey Nationals often goes into the first week of April and many Canadian post-season tournaments drag out as late as May. One note: August games will be recorded and will count towards the rating/rankings calculation process, but only until the first ranking in November. At this point in time, MYHockey excludes all August games from the rankings calculation.

MYHockey cannot be the roster police. Teams change their rosters almost every day of the year. If MYHockey were to take this issue to the extreme and create a new team every time a team changed its roster, the site would not work. So, while MYHockey really dislikes teams that add players for tournaments, we cannot and will not police this activity. The general rule is that a team is no longer a regular season team and becomes a special tournament team when it consists of three (3) or more players that are not regularly on the roster or if they have one (1) or more players and their tournament performance is 2.00 points greater than the rest of their season performance as measured by MYHockey. Note that someone will have to bring these situations to MYHockey's attention and ask that games be reclassified.

MYHockey assumes that once the season starts (September 1st, with some regional exceptions), all games played by the teams with sanctioned referees are real games and will be recorded in the system. There are some games that may not qualify, based upon various issues outlined in the MYHockey Game Definition Rules. Claims that your team was a tryout team, after the start of the season, are not sufficient to get a game removed. If you don't want games recorded in MYHockey that were played by a tryout team, then don't play them, or put coaches on the ice and not officials, thus making it look different than a normal competitive game. Otherwise, your opponent is likely to think it should count and MYHockey cannot research each and every one of these events (we tried it for a few years and failed). The only way to get a game removed is for the head coaches from both teams to send me an email requesting a score be removed.
