Soccer, Hoops Next to Seed Using MPR

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 – 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.


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 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.


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 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. “ 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.

Working Together, with Neighbor's Help, Schoolcraft Teams Making Selves at 'Home'

SCHOOLCRAFT — If it is a home game for the Schoolcraft football team, head over to Vicksburg.

Southwest CorridorIf it is soccer, go to Schoolcraft’s baseball field.

Things are a bit jumbled in the sports world for the Eagles this season.

With a new football field under construction and a new elementary school built on the site of the former practice fields, the two teams have been a bit displaced.

“Along with our football field, we had three practice fields that were utilized by a lot of our youth programs, Rocket football, youth soccer and our soccer and football programs,” Schoolcraft athletic director Bryan Applin said. “It’s taken a lot of understanding and flexibility from our coaches, players and our community to make it work out, and it has.”

Meanwhile, all four Eagles home football games will be played at Vicksburg High School.

If Vicksburg is home on a Friday, then the Eagles will play Saturday, including their Homecoming game this Saturday against Galesburg-Augusta.

The Eagles won their only “home” game so far, 33-14 against Kalamazoo United, and take a 3-1 record into Saturday’s contest.

The soccer team gave up its field to the football team for practices and has been practicing and playing their matches in the outfield of the baseball stadium.

For the soccer team, “It’s kind of an upgrade,” Applin said. “The soccer field they traditionally play on, they don’t have a scoreboard, they don’t have a bathroom facility, so we’ve been able to use the (baseball) scoreboard, the PA system, open up the bathroom building.

Schoolcraft’s Kolby Lloyd (10) works to break away from a tackler during a “home” game played at Vicksburg this fall. “The goal at some point is to give soccer a home, and we’re very, very excited about that.”

This year definitely has been challenging for the first-year AD, who credits Vicksburg athletic director Mike Roy with being a tremendous help.

“Mike Roy has been nothing but accommodating to us,” Applin said. “He’s been super helpful to me stepping in and assuming this scenario.

“The communities are so close, it almost feels like home for us.”

Roy said Jeff Clark, former Schoolcraft AD, reached out once the bond was passed for the new stadium last year.

“We had to make small accommodations as did Schoolcraft to make the schedules work,” Roy said. “By moving (Schoolcraft’s) games to Saturday, Vicksburg had to work with our Rocket football organization to make sure games were completed” before the Eagles varsity games.

Schoolcraft football coach Nathan Ferency said his team has been “rolling with the punches.

“These guys don’t care where it’s at; they just want to play football. We’re all taking care of each other. What a great place to be when everybody works together.”

When Jake Bailey heard the team would be playing at Vicksburg, “That got me excited,” the junior offensive tackle said. “They’ve got a really nice facility. I know the school will come out to support us no matter where we are, but it’s definitely different.

“Good thing we don’t play Vicksburg, although it would be fun because it would be both our home fields. The new facilities and being back at our home field at Roy Davis (Field next year) will be really fun.”

Vicksburg is Division 4, while Schoolcraft is Division 7.

Clockwise, from top left: Schoolcraft football coach Nathan Ferency, Schoolcraft boys soccer coach Jeremy Mutchler, soccer player Jack Curtis and football player Jake Bailey.The soccer team was “just being a team player” in giving up its own field for football practice, second-year head coach Jeremy Mutchler said.

“For the soccer team to be a team player and get behind the football team will help the community get behind the soccer team as well,” he added.

The biggest drawback is that part of the current field includes a piece of the baseball infield.

“The only odd thing is it is a smaller field, still regulation size, but smaller,” Mutchler said. “Part of the field is in the diamond, so we have to play in the dirt and it gets tricky, especially when you’re trying to throw it in or just play down the line.”

The move has cost the team a few home games.

“At the beginning of the year, we allowed schools, if they didn’t want to play here, we would go to their house,” Mutchler said. “We had to go to a few schools we would have played at home.”

Maintenance supervisor Eric McGehee was instrumental in preparing the field.

“He laid out exactly the parameters, so I was able to send that to all the ADs that were going to visit to give them an opportunity to decide whether that’s something they wanted to help us out for our home games,” Applin said. “A lot of schools were more than willing to come and play us to give our boys some home games. A couple wanted to be cautious and play on a more traditional surface, and we were able to make those arrangements as well.”

In only its second year as a varsity sport, the boys soccer team is still finding its identity, posting a 2-5 record so far.

Schoolcraft athletic director Bryan Applin has taken over the maneuvering of the teams’ home sites during his first year on the job.“We’re a very young team,” Mutchler said. “All juniors and freshmen. This is the juniors' second regular season. It’s all been a learning phase with maturity and sportsmanship.”

Junior captain Jack Curtis said he was a bit “bummed out” when he heard the team would move to the baseball field.

“The first practice, I drove over to our practice field,” he said. “No one was there.

“I drove over to the high school and saw everyone practicing (at the baseball field). I didn’t think a soccer field could fit on a baseball field.”

Curtis said in spite of the temporary move, “I’m just glad we can have some home games this year on Schoolcraft soil.”

As for Applin, he spent much of his career coaching basketball at both the high school and college levels and most recently worked as a salesman for Zeigler. His wife, Meredith, is an assistant coach for Western Michigan University’s women’s basketball team.

Ferency is appreciative of the work Clark and Applin have done to make this season’s changes relatively seamless.

“I’d like to highlight how great our athletic department is,” he said. “It takes a lot of moving pieces and parts to move people around and have a space for everybody.

“I’m really proud of our athletic department and all our coaches and kids for just rolling with the punches.”
