Performance: Mattawan's Casey Kirkbride

November 4, 2016

Casey Kirkbride
Mattawan senior – Soccer

Kirkbride watched Mattawan’s run to the Division 2 Semifinals last season from the sideline – as a junior on the junior varsity, and one of two goalkeepers on that team at that. But the 6-foot-1 senior has made himself into a player capable of helping the Wildcats take another step this fall, and his four MHSAA tournament shutouts including last week’s over No. 8 Holland earned Kirkbride the Michigan National Guard “Performance of the Week.” Mattawan entered the postseason ranked No. 11 in Division 2, and this week also shut out top-ranked East Lansing 2-0 to reach an MHSAA championship game for the first time in this sport.

After he and his team surrendered own goals three times during the first four games this fall, Kirkbride has gone on to notch 13 shutouts over the team’s last 22 games with a season goals-against average of 0.68 and 0.88 save percentage. He made nine saves Wednesday against the Trojans and has the Wildcats at 21-4-2 after they graduated 11 players including six all-staters off the team that finished 23-3-1 a year ago.

Kirkbride also played subvarsity basketball during his first two years of high school and should be in the running for academic all-state in soccer with a 3.73 grade-point average. He’s strongest in math and the sciences and is considering studying engineering in college, perhaps at Western Michigan University. But first, his team plays Dearborn Divine Child at 3 p.m. Saturday at Rochester Hills Stoney Creek for the Division 2 title.

Coach Kirt Brown said: “He played JV for me last year and showed determination. He’s just got a great attitude. I talked to him (Wednesday) night; he was the first kid I went after when they were all hugging each other, and (I asked) if he would have thought at the beginning of the year he would shut out the number one team in the state semifinals. He’s been dynamite; he’s got a good defense in front of him, but he’s made some great saves as well. He’s long and rangy, and he’s got that never quit attitude. He’s kinda measured, and he’s learned and he’s grown as the year has gone on. He knows how important he is to our team, but he’d be the first to say ‘I have a really good defense in front of me.’”

Performance Point: “I’m just really thankful to have a good defensive line that limits the chances opponents have,” Kirkbride said. “They haven’t had too many clear opportunities where I’ve had to come up with saves, and I’m thankful for that. I try to keep (my defenders) organized, but they did a good job of being focused and really just staying strong on their marks; I try to help on that too. The one (save) that sticks out (from last week) is when the ball hit the post … I was in mid dive and it just went past my fingers and came back and hit off my face, and then it goes off for a corner. I was just thankful it didn’t bounce off my nose or a different part (and into the net).”

New team, all team: “I think (our success) comes down to being more of a team on the field because when we have chances to go forward we make the most out of them and we don’t give the ball up as much. We’re just on the same page more defensively and offensively. Having that sense of knowing teammates know what you want, because when you have the ball, they know how you want them to play. And we don’t have selfish players; for the most part, all of us are selfless and the goal is for the team.”

On the move after Marshall: “Beating Marshall in the Regional Semis, it’s pretty close to greatness. We were outsized – they had some really big kids, and we never really had to face too much of that before. Seeing how we could handle it, we just played through it. We ended up conceding a goal right after halftime, but we didn’t drop our heads at all. Determination is really what that is. Our personnel, I’ve seen a lot of great things from these players, so I know we’re capable of it.”

JV as a junior: “It was tough last year because I was goalie part of the time, and another guy was goalie part of the time, and sometimes we didn’t know until the day of the game who would play, or that one would play one half and one would play the other. I kinda didn’t want to play goalie, but I definitely would not question if Coach wanted me. … I wasn’t so confident in myself (this season), but seeing (my teammates) were, that meant something to me. That’s how (important) being on a team of friends is. (I learned on JV) how important it is to make connections with your teammates. At the beginning of (last) season I didn’t have too much connection to my other teammates, but as the season progressed it got better.”

Quick thinking: “Playing goalie, you need to know decision making. Know the pros and cons without even thinking, that definitely comes into effect. If I have a decision in my mind, I’ll do it.”

Soccer, Hoops Next to Seed Using MPR

August 6, 2019

By Rob Kaminski
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.
