Thompson Erases Doubt, Makes History

When Jacara Thompson tore the anterior cruciate ligament in her left knee this past summer, she thought she was done playing basketball.
The fact it was the second torn ACL of her high school career, along with the timing of the injury, had the Swartz Creek superstar doubting her future.
“I thought I wasn’t going to play basketball anymore,” Thompson said. “This is my second knee blowout and I need to be done – that was my first thought. I was going to miss my whole senior year, and that was really hard.”
Thompson proved her initial thoughts wrong, however, and is back on the court making history. Recently, she broke a school record that had stood since 1979, setting the all-time mark for scoring at Swartz Creek. She had scored 1,179 career points through Feb. 10, now well ahead of the former mark of 1,087.
“I don’t even know how to explain it,” Thompson said of setting the record. “Nobody in my family has ever broken a big record like that or anything. It really didn’t hit me until people started telling me congratulations.”
Those congratulations would have been well deserved for any player hitting that mark. For those who have watched Thompson overcome two major knee surgeries and break the record despite missing 17 games, the moment was even more special.
“I was extremely proud,” Swartz Creek girls basketball coach Adrian Trzebiatowski said. “As a player, you have a tremendous amount of respect for anyone that achieves that goal. As a coach, to see a young woman grow up, to blossom, to develop into a very good basketball player and an amazing person, it is an extreme sense of pride and admiration for what she’s gone through.”
It was in Trzebiatowski’s second season at Swartz Creek that Thompson entered high school, and the slashing guard was making an impact on the varsity team as a freshman. But her debut lasted only six games as Thompson’s first torn ACL, in her right knee, came early in her career.
She came back with a strong sophomore campaign, and as a junior joined the state’s elite, averaging 25 points per game and totaling 501. She was named Class A all-state second-team by The Associated Press.
“Early in her career she was a slasher – she could take a bump or two or three and still get to the basket,” Trzebiatowski said. “Last year we really committed to lifting weights, and she could finish with contact. She was able to get herself to the line and finish layups. I wish there was a stat column for how many and-ones she has. She was a strong player who could really plow and weave her way to the basket.”
Thompson also was developing a stronger mid-range game and working on her outside shot to keep defenders even more off-balance. Before she could showcase her advancing skills and build on the momentum of her junior season, she suffered her second ACL tear.
While an initial doubt she could return again was in her own mind, it was something her coach never saw.
“She knew how to rehab, and knew what she had to do to get back,” Trzebiatowski said. “As far as mental toughness, Jacara overcoming this is probably one of the toughest athletes I’ll ever coach.”
As Thompson worked her way back again, she said it was her Swartz Creek teammates who helped her get to the right place mentally.
“I finally got over it when I started to practice with my team,” Thompson said. “I couldn’t scrimmage with them, but they made me feel even better, that you’re going to be even stronger when you come back.”
Trzebiatowski said the team had to learn to play without Thompson over the summer, but despite that, Thompson’s impact on the young Dragons squad remained strong.
“Everybody looked at her as a leader, but I don’t think she’s always felt that way until this year,” Trzebiatowski said. “When we actually voted for team captains, the team decided before we even voted that Jacara would unanimously receive the vote for team captain. That’s never happened to me.”
Thompson missed the first two games of the season, but has come back strong. She’s averaging 17 points per game and has now added a more dangerous 3-point shot to her repertoire, something she said already has caused opposing defenders to take notice.
“I kind of always knew I had to get better at it,” she said. “Shooting wasn’t really my big thing. I always loved driving and getting to the basket and to the free throw line, but I knew I had to add an outside game. I feel like (defenders) look for me to go the basket every time, but now that I have an outside shot, they’re going to have to check me. They’ve caught on. They call me a shooter now.”
She said she feels like her old self now, although it took a while to get there.
“I’d say probably about 90 percent of it is mental, really,” Thompson said. “Because you have to think about what move am I going to do? Am I going to tear my ACL again? You think about every move you do when you’ve been through two ACL surgeries.”
Thompson is undecided on her basketball future, but said she wants to play at the college level. Her injuries have helped her to focus on her off-court future, however. No matter where basketball takes her, Thompson wants to study to become a physical therapist.
“I had always thought about going overseas and even trying to make it to the WNBA,” she said. “I don’t think I want that anymore. I want to do something to help people with ACL injuries.”

Soccer, Hoops Next to Seed Using MPR
August 6, 2019

MHSAA benchmarks editor
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.
