P-W Finishes Historic March Atop D3

EAST LANSING – Collin Trierweiler found himself outside with his older brother again, firing up free throws, one of his favorite things to do when he was younger.
Except this time, he was standing at the free-throw line at the Breslin Center, with no one else on his side of the court, less than a second remaining on the clock, and Pewamo-Westphalia’s first MHSAA Finals championship hanging on the shots he was about to take.
A meeting of undefeated finalists came down to the slimmest of margins Saturday at the Breslin Center. Trierweiler, on the line after an intentional foul was called on Iron Mountain with seven tenths of a second to play, made it through two timeouts before sinking the first shot, and a third timeout before making the second to put the Pirates ahead 53-52 and all but ice the Division 3 championship.
Trierweiler hadn’t practiced all postseason, and sat out multiple games with an ankle injury. But he played 26 minutes in the Final, on the court when it counted most.
“As a senior, right around the time when I get hurt, right as the playoffs start, it was frustrating, Trierweiler said. “Coach said it would be best to sit out the practices and just fight through the games. Every game I just had my teammates on my back saying you’ve got this, you’re fine, just keep playing the game. And when I was feeling pain, they’d help me forget about it.
“The free throws, I just tried to calm myself down and think about myself out in the driveway with my older brother. We used to practice all the time, and it was one of my favorite things to do. I always dreamed of a moment to be put on the free-throw line, a big moment. Maybe not quite this big, it was a little scary, but I tried to just block out the background, see the trees in my yard, and put them up and shoot them in.”
P-W (28-0) previously had finished Class C runner-up in 1993 and 2014.
Trierweiler entered this week making 59 percent of his free-throw tries this season.
But his absence from normal practice activities the last few weeks may have been a blessing in disguise.
“When he’s been sitting out, he’s been shooting free throws. I had him shooting free throws again (Saturday),” P-W coach Luke Pohl said. “Was I a little leery? Not really, because he’s a pretty tough-minded kid.
“I remember his mother telling me this season, (that) when he was just a little boy, he’d be dribbling the basketball in front of his mom saying, ‘Mom, someday I’m going to be the point guard at Pewamo-Westphalia,’ and he was so proud of that.”
The Pirates had led most of the first five minutes of the first quarter, but didn’t lead again until Trierweiler’s free throws at the end.
Iron Mountain (27-1) led by as many as eight points during the second and third quarters and by six multiple times during the fourth. Pirates senior Andre Smith took a six-point lead to three with a 3-pointer with 1:44 to play. After Trierweiler missed two 3-point tries to tie the score, he went in for a layup instead with 22.7 seconds left to bring the margin down to one.
Two free throws by Mountaineers’ sophomore Foster Wonders pushed the lead back to three, but again Trierweiler scored with 11.5 seconds left to make the margin one. Iron Mountain broke the ensuing pressure but was called for a travel, and on P-W’s last attempt to get down the court for a final shot, Trierweiler drew the intentional foul.
The ending was emotional for obvious reasons. Pohl said his heart went out to Iron Mountain. But he believed if Trierweiler hadn’t been fouled, he would have scored.
The Iron Mountain contingent certainly was disappointed, but completed a memorable run that saw the Mountaineers defeat last season’s Class C champ Detroit Edison in the Semifinal on the way to Saturday.
“We put in tremendous effort. It didn’t just start this year – it’s been going on for years with these guys,” Iron Mountain coach Bucky Johnson said. “Their effort has never been in question. I’m really proud of them for that. Pewamo, great effort by them too.”
Smith finished with 21 points, including five 3-pointers, for P-W. Junior Aaron Bearss had 15 points and eight rebounds.
Wonders scored a game-high 20 points for Iron Mountain, and junior Marcus Johnson had 17 points, six rebounds and three assists.
“I thought our kids played awesome,” Bucky Johnson added. “They went toe to toe, both teams. Give them credit, give us credit, what do you say? … It’s part of the game. It stinks to be on this end of it.”

Past Wildcats Bringing Valuable Experiences Home as Three Rivers' New Hoops Coaches

THREE RIVERS – Basketball has always been a passion for rookie Three Rivers coaches Drew Bosma and Michael Morrison.
The two former Wildcats aim to bring that same level of energy they exhibited during their playing careers as they embark on their first varsity coaching stints.
Both Bosma and Morrison have brought along a few familiar faces as they begin working to rebuild Three Rivers' strong basketball tradition.
Bosma, a 2009 graduate, replaced long-time mentor Brian Burg as the Wildcats' varsity boys coach, while Morrison has taken the reins of the girls program from Carley Shoesmith.
As a student-athlete at Three Rivers, Bosma excelled in football, basketball, baseball and track & field. He continued his playing career at Alma College and Liberty University before returning home and completing his undergraduate studies in psychology through online courses.
"My psychology background has been useful in my coaching career. The kids you work with have so many different issues they encounter than when I was in school," said Bosma, who is employed in the RV Industry at Grand Design in Elkhart, Ind.
Bosma's early shift works out perfectly with his coaching duties. After 11 seasons as Three Rivers’ JV boys coach, he spent the last two as a varsity assistant at Portage Northern. His immediate goal is to renew enthusiasm within the program.
"My experience with Three Rivers basketball as a player was a very good one. I want to build the culture to the point where people want to be here, the effort isn't questioned and (we) have kids who enjoy the game," Bosma said. "I've had a lot of good mentors in this game. Now that I'm a head coach, I want our players to be able to step onto the court and play freely. Yelling after every mistake they make isn't going to teach them anything. They are going to make mistakes in life, and they have to understand it’s ok to mess up and learn from those mistakes.”
Bosma's additional goals this season are simple ones.
"I want our kids to make it known that we have competed hard in every game with a no-quit attitude. It's a coach’s dream to win every game, but I want to make sure these kids are becoming better people as well as basketball players," Bosma said.
Long-range goals include increasing interest among students to try out for the team. He and his staff have organized the Three Rivers NextGen Boys' Basketball Program for students in kindergarten through eighth grade that will begin in January and focus on building skills and nurturing players who may fill the ranks down the road.
Bosma's coaching philosophy includes being tough on his players while showing that he truly cares about their well-being.
"As a coach I'm going to be hard on you, but these guys know that it’s out of love and concern for them,” he said. “They understand that anything I say to them is meant truthfully, and it comes from the heart. I want them to know they can come and talk to me. I want them to return 10-12 years later and notice the same type of feeling in this program. All of my coaches are either former teammates of mine or guys who played for me.”
Tirrell Hausmanis, a former hoops star at Three Rivers, serves as Bosma's varsity assistant. Brenden Brown is the Wildcats' junior varsity mentor, and alumnus Thomas O'Dell is the freshman coach.
"Having Three Rivers alumni on our coaching staff teaches these kids how important basketball is to our community," Bosma said.
Offensively, Bosma expects the Wildcats to be able to stay in space and use their long wing players and better shooters to their advantage. Among the top returners are junior point guard Brayden Carpenter, 6-foot-6 senior forward Zander Barth (who is committed to Central Michigan for football), and senior forward Carter Langston.
Carpenter averaged 13 points per game as a sophomore, as Three Rivers finished 7-15.
"You can tell there's a different attitude under the new coaching staff. There are lot of guys now who want to put in the extra time and energy to get better,” Carpenter said. “Our communication on the court has improved, and Coach Bosma's system allows us to play freely without worrying about the consequences of making a mistake.”
Three Rivers looks to be more adaptable at the defensive end.
"Defensively I want to change things up all the time. We don't want to just sit back in one zone or play man-to-man, but rather press whenever we can,” Bosma said. “We have a group that has improved its basketball IQ, which allows us to do so much more as coaches. We have good team camaraderie and kids who are going to play for each other. These guys are more excited about getting the win rather than what shows up in the box score.”
Bosma has seven seniors on his roster, but Three Rivers still is a fairly young team in terms of experience.
"We have long and athletic kids and guys who could be pretty good once they build their confidence level. We have great guards and kids who like to defend. Defense has become somewhat of a lost art in high school basketball. We have the tools though to be a successful basketball team," Bosma said.
Morrison, a 2003 Three Rivers graduate who played football, basketball and baseball for the Wildcats, has taken the reins of the girls program. After high school, Morrison attended Ferris State University where he graduated with a psychology degree as well. He is employed as a probation officer for the state.
Morrison has extensive experience coaching basketball. He started out coaching travel basketball in Paw Paw while also coaching high school teams at Kalamazoo Loy Norrix, Vicksburg and Three Rivers, including the last five years as the JV boys coach under Burg. He also served as an assistant men's coach at Glen Oaks Community College under Mike Elliott.
"Working under Mike taught me so much more about basketball and has made me an even better coach. That time was very beneficial," Morrison said.
Morrison's immediate goal is to provide stability in the girls program.
"These girls have had several coaches in the last few years. I want to provide some stability and help the program grow from the lower levels,” he said. “Obviously you want to win championships, but right now we have to start with attainable goals like finishing over .500, which we haven't done in a while.”
Other goals that Morrison feels are within Three Rivers’ grasp are finishing in the top half of the Wolverine Conference and competing for a District title. The Wildcats were 8-14 last season and tied for sixth in the league.
His philosophy centers around pace and space.
"I want to get up and down the floor and defend. We want to execute an offense in the halfcourt, but also get up and down the floor and get some fastbreaks when we can. We spent the first couple weeks of practice working on executing things the right way," Morrison said.
Senior guard Dani Glass, a second-team all-Wolverine Conference pick last season, returns for her fourth varsity season. Glass, who averaged 12 points per game as a junior, has committed to play at Kalamazoo Valley Community College.
"Dani makes us go and is our catalyst for everything we do offensively. We expect more from her this season as she gets ready for the next level," Morrison said.
Sophomore post player Braylee Burg will be another key component for the Wildcats, along with senior defensive specialist Jersey Roehrs.
"I feel I help my team most with my ability to box out and create a lane for my guards along with providing rebounding. I want to work on finishing stronger at the rim this year,” Burg said. “Our coaching staff has us doing fun drills that are getting us ready for the season. We want to get the ball down the floor more effectively and set up our offense."
Morrison is most excited about his team's work ethic.
"We are very excited about this team's potential and are really leaning heavily on our seniors to give us a big great burst of energy and bring everyone else along,” Morrison said. “People are going to see a very well-disciplined group that works hard and together as a team. We are working extremely hard on our communication and shooting as well."
Parker Ellifritz, who ranks among Three Rivers’ all-time leading scorers, serves as Morrison's varsity assistant. Olivia Hancock, whose played on the 2016 Class B championship team at Marshall during her prep days, fills the role of junior varsity coach with Payge Ellifritz, Parker's sister, serving as her assistant.
