DeBoer Looks to Steer Sailors to Breslin

CUTLERVILLE – Jenn DeBoer remembers the thrill of playing in the MHSAA Class B Final when she was a sophomore.

The South Christian standout would like nothing better than to revisit that feeling in her final season.

DeBoer, a 5-foot-7 point guard, is currently leading the Sailors toward what they hope is another extended postseason run.

South Christian is 16-1 with three games remaining in the regular season before Districts tip off in March.

“That was a lot of fun, and obviously it was different because I was a sophomore and I knew that I had two more years after that,” DeBoer said. “But this year it’s a big goal for all of us seniors. We’ve talked about how we want to get back there and end our senior season strong.”

Led by DeBoer and a cast of veteran senior teammates, the Sailors have displayed the potential to make some noise in the MHSAA tournament.

They’re seeking an Ottawa-Kent Conference Gold title and currently own a perfect 7-0 mark in league play. Their championship hopes hinge on upcoming showdowns with Wayland and Grand Rapids Catholic Central.

“It’s been a blast so far,” DeBoer said. “I couldn’t ask for a better senior season. Our team chemistry is so amazing, and the other seniors and I get along so well. Obviously, winning has been fun too, and it’s probably one of the best teams I’ve been on.”

DeBoer, a four-year varsity player who committed to Division II Grand Valley State University before her junior season, has been the floor general of this year’s squad.

She has contributed in every aspect of the game, averaging 16.8 points, 6.0 assists, 4.6 rebounds and 3.8 steals per contest.

First-year South Christian coach Kim Legge has watched DeBoer improve and mature throughout the past years.

“She has made strides because of her work ethic, and she always wants to learn,” said Legge, a longtime assistant under recently-retired coach Jim DeBruyn.

“She’s like a sponge, and she’s been to a point guard camp the past two summers. That has really helped with her decision-making and leadership skills.”

DeBoer recently established two new school records for her 3-point shooting prowess.

During a recent win over Hastings, she set a new mark for career 3-pointers that had stood since 2003 while also surpassing the single-season record.

DeBoer toppled Leah Pettinga’s career record of 93 3-pointers made. She currently has 45 on the season.

“It’s a huge honor to have the record now,” DeBoer said. “I knew I was pretty close because I focus on shooting 3s. It’s my favorite thing to do, and that’s just what I do. I wasn’t sure if I would ever make it, so it is definitely really cool to know that I have the record now.”

Legge didn’t know DeBoer was approaching the milestone until a few weeks ago, but she wasn’t surprised by the accomplishment.

“Anything that girl puts her mind to she seems to get done,” Legge said. “I got clued in a couple games before that she was getting close, but she would have never said anything to me. That’s how she is. She is so humble. It was a goal of hers, but it never would’ve come out of her mouth.”

DeBoer said the transition from DeBruyn to Legge wasn’t a difficult one.

“They both have similar coaching styles, but coach Legge is a lot more centered on defense so our defense this year has really picked up,” she said. “We have done a lot of the same things we’ve been doing in the past.”

DeBoer’s early commitment to the Lakers has allowed her to enjoy a stress-free final two seasons. It’s allowed her to focus strictly on helping her team succeed instead of lamenting over which college to choose.

“The pressure has been off, and I’ve been able to focus on my last basketball season at South,” DeBoer said. “The last four years have gone by pretty fast, and it doesn’t feel like I’m a senior until I think about it and look at old pictures. In a couple months I will be graduating, but I’m trying to enjoy high school while I’m still here.”

DeBoer is anticipating the jump to college, but is committed to ending her career on a high note.  

“I’m definitely looking forward to playing in college next year, but I would really like to have a good ending to this season,” DeBoer said. “If we keep working hard, then I think we will do pretty well in the postseason.”

Legge isn’t one to look ahead, but with a starting line-up consisting of all seniors, expectations are high for the remainder of the season.

“We have a hard road ahead of us the last week of conference (play) and I don’t feel like we have peaked,” she said. “I really focus on what my team needs to do to grow on a day-to-day basis. Every coach in the state hopes their team makes a tournament run, and at this point of the season, it’s a goal of ours.”

Soccer, Hoops Next to Seed Using MPR

August 6, 2019

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.
