As the topic of seeding for MHSAA Tournaments continues to swirl in the air of numerous committee meetings on an annual basis, one of the primary concerns continues to focus on the simple question: “How?”
The MHSAA for years has been working behind the scenes on potential formulas which could best be used as a standardized tool to assist in measuring strengths of teams in a given sport.
This spring, the MHSAA introduced the Michigan Power Rating in the sport of Boys Lacrosse. The Representative Council approved limited seeding beginning in 2019-20 for girls and boys soccer and girls and boys basketball, and MPR will be the metric to determine which two teams must be seeded on opposite sides of District brackets in those sports.
“The boys lacrosse tournament has been seeded since it was added as an MHSAA-sponsored sport in 2005. The seeding is done by committee based on several criteria, one of which was statewide power rankings generated by a third-party website. In the Fall of 2018, that website ceased operation – it was the perfect opportunity for the MHSAA to develop its own data-driven, purely objective ratings system and incorporate that data into the seeding criteria,” said Cole Malatinsky, administrative assistant for the sport.
“The benefits of the new MPR system have been already mentioned – it is MHSAA controlled, simple, objective, and transparent, and it can be used by other MHSAA sports in the future.”
MPR is a computer rating formula similar to the popular RPI rating. MPR provides a way to measure a team’s strength relative to other teams, based on games played against other MHSAA tournament teams, largely on the strength of their opponents’ schedules. MPR is purely objective using only the game results listed on MHSAA.com – there is no subjective human element.
What is the basic MPR formula?
MPR is calculated using wins, losses and ties for games played between teams entered into the MHSAA tournament. The final MPR number is 25% of the team's winning percentage, plus 50% of its opponent's winning percentage, plus 25% of its opponent's opponent's winning percentage.
MPR = (.25 x W%) + (.50 x OW%) + (.25 x OOW%)
The MPR formula can be applied easily to other MHSAA team sports.
What game data is included in the formula? What game data is not?
MPR looks only at results between opponents entered into the MHSAA postseason tournament. Wins, losses and ties in multi-team shortened game tournaments (lacrosse, soccer) also count. Forfeits also are counted as wins and losses.
MPR does not use the specific scores of a game or the margin of victory in a game. The location of a game is not included in the MPR formula, and the formula weighs results at the beginning of the season the same as results at the end of the season. Scrimmages are not included.
Why use the MPR formula?
Different rating systems have been used in the past or have been recommended to the MHSAA. We wanted to have a rating system where the data was controlled and stored in house and could be used for any sport featuring head-to-head competitions.
With its own rating system the MHSAA also can control the different components of the formula, thus keeping the tenets of scholastic competition at the forefront (like not including margin of victory in the formula). Finally, by listing all scores and team schedules online, as well as showing the MPR calculator on each team schedule page, the ratings are transparent and can be replicated easily.
CALCULATING MPR
What are the detailed components of the MPR formula?
You need three numbers to calculate your MPR: winning percentage (W%), opponent’s winning percentage (OW%) and opponent’s opponent’s winning percentage (OOW%).
How do you calculate winning percentage (W%)?
Divide the number of wins by the number of total games played. A tie is worth half a win. For MPR purposes, find the winning percentage against all teams that will play in the MHSAA tournament (MPR W%). Games played against out-of-state teams, varsity “B” teams, junior varsity teams, non-school club teams, and any other non-MHSAA tournament participants should not be included when calculating winning percentage. W% should be an easy number to calculate.
How do you calculate opponent’s winning percentage (OW%)?
Average the winning percentages of a team's opponents. When calculating the winning percentage of a specific opponent, use the opponents "Adjusted Winning Percentage" (ADJ W%). Adjusted winning percentage eliminates all games the team played against that opponent (as well as its games against non-MHSAA opponents).
For instance, if the team beat an opponent with an overall record of 4-1, use a record of 4-0 (1.000) for that opponent. If the team lost to an opponent, use a record of 3-1 (.750). Find the ADJ W% for all opponents, and then take the average. If a team plays an opponent team twice, that opponent’s ADJ W% will be counted twice.
OW% is not calculated via the combined record of the opponents; instead take the average of all opponent’s winning percentages.
How do you calculate opponent’s opponent’s winning percentage (OOW%)?
Use the same process described above, except calculated for the opponents of a team's opponents. This number is much harder to manually calculate, so the OW% for every team is listed on the MPR page of the MHSAA website.
Again, simply take the average of all opponent’s OW%.
How often is MPR calculated?
MPR is calculated about every five minutes. Enter a score and a minutes later the team MPR and the MPR of all the team's opponents will update.
How much will my MPR change throughout the season?
You will see wild MPR swings in the beginning of the season, but after about 10 games played your MPR will start to level out. At 20 games played you will see very little movement with each additional game played.
My score is missing. How can it be added?
This is a crowd-sourced system. Any registered user of MHSAA.com can add a missing score. ADs, coaches, parents, students and fans all can login and enter a score for any game.
What are some common errors when calculating MPR?
When calculating your team’s winning percentage, only include games against MHSAA-tournament teams. When calculating your opponent’s winning percentage, don’t include the games they played against you. When calculating ties, count the game as a half-win and half-loss.
What happens if a game is cancelled?
Because the MPR system works off of averages, it will not make a difference in the final MPR if a game cannot be rescheduled. It would not penalize, nor benefit, any team involved in that scenario.
USING THE WEBSITE
Where can I find game scores?
A list of statewide scores for all sports can be found in the MHSAA Score Center. To find a schedule for any team click on “Schools & Schedules” in the top navigation bar, search for the school, then once on the school page click the sport. You can also see a list of all schools (with links to schedules), on the statewide MPR list.
“We continue to have great success in score reporting for varsity boys lacrosse contests. While we state that schedule submission and score reporting to MHSAA.com are required, athletic directors and coaches understand that in order for MPR data to be accurate, we need consistent and accurate score reporting,” said Malatinsky. “MHSAA.com is now the primary site for high school boys lacrosse schedules, results and ratings in the state.”
How should I use the statewide list of teams and MPR?
Linked to the boys soccer page (and eventually to be added for both basketball pages and girls soccer) is a statewide listing of all Michigan Power Ratings (MPR) for teams entered into the MHSAA postseason tournament for that sport. Linked on the MPR page is an explanation of the District draw formula, describing when and how teams will be placed on the bracket.
The MPR data updates every five minutes. Click on the column headings to sort the data. You also can use the drop-down menu to show teams in one Division, or type a District number in the box to filter teams for that District (Region for boys lacrosse).
You also can click on any school name to go to its schedule page.
How do I read the school schedule page?
The schedule at the top of the page shows the date and opponent for all scheduled games, and results for games already played. If results are missing, click “Submit Score” to add a game score.
Below the game schedule is the MPR Calculator. The calculator is split into three sections. The first section shows the three MPR component scores for the team, as well as the team’s current MPR score. The second section shows the MPR information for the team’s opponents – specifically, for the opponents the team already has played (actually, for games where scores have been submitted). Only these games are included in the MPR calculation.
The third section highlights future opponents. The MPR data for future opponents are not used in the MPR calculation for the team.

Yale Athletics Completes Banner Winter with 3 Record-Setting Seasons

Whatever dollar number Chace Palmateer had next to “banner updates” on the 2024-25 Yale athletic department budget, it’s not going to be enough.
But after a record-breaking winter for the Bulldogs, he’s not really concerned with costs.
“We have six (titles to add) for winter alone, and that’s not including that we had a pretty good fall with cross country,” Palmateer said. “It’s a fantastic problem to have, and truthfully, I hope we have more in the spring.”
Yale’s wrestling, boys basketball and girls basketball teams each completed perhaps the best seasons in their respective program histories this winter, smashing team and individual records along the way.
“That energy among our student-athletes was phenomenal this winter,” Yale boys basketball coach Garnett Kohler said. “That’s one thing about our Yale community, we all support each other. We’re all Bulldogs, through and through, and we love to see each other have success. I thought we kind of fed off each other’s success, too. The wrestlers got going really good early, and that kind of set the stage, then us and the girls got going.”
Yale’s wrestlers were runners-up at the Division 3 Team Final, their best finish ever. The boys basketball team set a record for wins in a season at 22, won the Blue Water Area Conference and District titles, and advanced to the Division 2 Regional Final for just the second time in program history. The girls also set a record for wins in a season at 22, shared the BWAC title, won a District and advanced to a Regional Final for the first time.
“The atmosphere in the school was great,” Yale wrestling coach Rob Majcher said. “So many programs were having so much success because of the work they put in. It’s nice to see that hard work that the kids and coaches put in really paid off for them.”
Majcher’s team was the first to make its postseason run, winning its second-straight Regional title with a dramatic 32-31 victory against BWAC rival Algonac.
The Bulldogs defeated Adrian Madison in the Quarterfinals and Lake Odessa Lakewood in the Semifinals at Kalamazoo’s Wings Event Center before running into an all-time great Dundee team in the Final.
“It meant everything (to get to the Finals),” Yale senior 120-pounder Landon Sopha said. “Everything I’ve done throughout my life was all coming down to that moment for the team. It was just pure joy and excitement, not only getting that mitten (trophy), but thinking of these next years and how great Yale wrestling can be.”
Sopha was part of a record-tying six boys Individual Finals qualifiers for the Bulldogs, and one of five to place, as he took third at 120. Mackey McClelland (113) placed second, Cole McLaughlin (165) placed third, Logan Rhodes (120) placed fourth and Kersten McClelland (132) placed fifth. The five boys placers were second-best in program history, and if you add Gianna Hoskins (105) and Ember Marriott (190), who both placed sixth in the girls tournament in their respective weight classes, the seven total would be an all-time best.
Throughout the year, the Bulldogs set program records for most individual varsity matches won (798), takedowns (1,485) and varsity pins (475) in a season.
McLaughlin set the record for most first-minute pins in a season at 24, and Kersten McClelland had 536 match points, a school record.
“We told the kids, ‘You stick with this, and you will do good things,’” Majcher said. “As a coach, it’s definitely fulfilling to see a group of kids that did stay and did achieve what they were able to.”
Then there was Sopha, who finished off a record-breaking career for the Bulldogs. He became the first in Yale wrestling history to advance to the individual semifinals all four years, the second four-time all-state finisher, fourth four-time Finals qualifier, third four-time BWAC champ, and the all-time leader in career match points at 1,354. He also became the second Yale wrestler to reach the 200-win mark.
“It means a lot,” Sopha said. “For me, it’s something that I’ll be able to look back on forever. It’s something that I’ll hopefully be able to watch people in the future break. It’s pretty cool.”
As wrestling season wound down, the boys basketball team found itself re-writing its own program record book.
Yale finished 22-4 on the year, winning a record 19 regular-season games and setting a program record for consecutive wins with 14. It was a season that surprised Kohler.
“We lost eight seniors from last year, and they had a lot of success on their own,” he said. “We had a lot of new guys coming in, and I did know they had some talent and had some success coming up through the younger ages. I knew we could eventually be good, but I didn’t expect the season-long success we had, strictly because we were so young and untested. That’s really a testament to what (seniors) Ryan Fisher, Clayton Harmon and Blake Bowman were able to do. They were able to get those other guys to buy into that real early, and everybody kind of fed off their leadership.”
While the team was setting records, junior guard Jackson Kohler was lighting the individual record book on fire.
He set marks for points (560), steals (82) and 3-pointers (76) made in a season, as well as points (1,164) and assists (417) for a career.
“Obviously, I’m a team guy, so I wanted the league championship and the District championship, but it’s always good to have accomplishments along the way when you’re winning,” said Jackson Kohler, who is Garnett’s son. “Being a little kid growing up when he was coaching here earlier, I was always watching the older guys practice and how they would go about practicing and how they would be in their games. I always looked up to them and just worked and worked to get to where I am now.”
As Jackson was setting records on the boys side, his classmate Sadie Dykstra was doing the same while leading a record-setting Yale girls team.
Dykstra, who won the long jump and 300-meter hurdles at the Lower Peninsula Division 2 Track & Field Finals in 2024, also became her program’s all-time leading scorer this season, sitting at 1,248 after her junior year.
She’s the Yale girls basketball record holder for points in a game (38), field goals in a game (14), free throws made in a game (12), points in a season (596), scoring average in a season (22.9) and field goals made in a season (217 prior to the Regional Final).
“I think it was super cool – this doesn’t happen very often where you can (go) from the girls side to the boys side and see records being broken by two individual players,” said Dykstra, who admitted that her record-setting season hadn’t really sunk in yet. “I’m going to be honest, it’s probably not even hit me yet that our team went that far to the Regional. Of course, I’m super excited, but I just know I have so much more to give. I’m really looking forward to next season.”
For Yale girls basketball coach Jason Leonard, who spent time with the boys program before taking over the girls head coaching job a year ago, seeing Kohler and Dykstra excel at the same time has been a joy.
“You don’t get to see that – you’re lucky to see one on one side, boys or girls,” he said. “To me, they’re the two best players in the area, and it’s a pretty cool thing to see. I’ve seen Jackson come up on the boys side and as a freshman, he had a huge impact. It’s pretty cool to see and pretty cool for the programs and the community to have them leading their teams to a new level.”
Of course, Dykstra’s records were just the tip of the iceberg for a team that was also experiencing a record run.
The Bulldog girls tied their program record for BWAC wins (13) and regular-season wins (19), while setting the mark for total wins. They also set records for free throw percentage (63.96 percent) and field goals made in a season (551 prior to the Regional Final).
Dykstra also wasn’t the only record-breaker on the team, as senior Alyssa Barr became the program’s all-time leader in career rebounds and blocks with 690 and 74, respectively, heading into the Regional Final loss against Country Day.
“I think we exceeded expectations,” Dykstra said. “I don’t think anybody thought, ‘Oh, they’re going to get to the finals of Regionals,’ just for the fact that we matched up with Armada in the first round of Regionals. I think we definitely exceeded expectations coming from more of other people’s standpoints. For me, I think we met my expectations, because we weren’t going to lose to a team (Armada) two out of three times.”
Regardless of the expectations any of the teams had coming into the season, one thing is certain: It was a winter nobody in Yale will soon forget.
“I will say, we’ve had very good teams come out of the Thumb, and different schools have had different teams succeed at different times, but I don’t remember a school having across-the-board success like we had this winter with the three teams,” Garnett Kohler said. “In schools like ours, talent gets spread out across the groups, and talent comes in waves. To do it all in the same season, it’s pretty fun to watch.”
