Tri-unity Ends Historic Run in Quarters
March 16, 2016

WYOMING – When the month of March rolls around at Wyoming Tri-unity Christian High School, it’s traditionally been a time for the community to rally around the boys basketball team for a lengthy postseason run.
The boys team has been a perennial state powerhouse in Class D for the past 20 years, winning four MHSAA Finals (1996, 2002, 2006, 2011) and earning four runner-up finishes.
This season, however, the girls basketball program enjoyed similar success with its own jaunt through the Class D tournament.
The Defenders won their first MHSAA Regional title last week with a 58-46 win over Climax-Scotts, upping their winning streak to 13 games after an 8-4 start. Tri-unity’s historic campaign ended Tuesday night with a disappointing 71-30 loss to unbeaten Pittsford in a MHSAA Class D Quarterfinal.
"Our goal was to do this,” Tri-unity coach Bryan Sinner said. “This is my third year, and our goal coming in was to bring some respect to the girls’ side of the program and that’s what we’re doing. The boys are going on a run, and we’re on a run, and it’s been fantastic for the school, especially for these girls now.”
The Defenders finished with a 21-5 overall record, and the banner season was something they knew was possible at the start of the season.
“I knew we could go far as long as we worked together,” said senior guard Sarah Buffum, a four-year varsity player who averaged a team-high 17.5 points per game.
“We had the talent, but we just had to come together as a team. We knew we could do it, and winning Regionals was so special, especially since it was the first time in school history. It meant a lot.”
Tri-unity’s other senior, center Marissa Stevenson, said it was thrilling to become the first team to reach the Quarterfinals.
“It was exciting to be noticed and make history for our school,” she said. “I think we were all in a lot of shock when we won, but throughout the season we learned our team chemistry, and our defense really picked up in this tournament. I had so much confidence in our team.”
Said Sinner: “They felt pretty special after that win, and they worked extremely hard for it. It’s a true blessing that we were able to do that, and the support from our fans and community has been fantastic. It’s gone back and forth between the girls and the boys, and it’s really great for our small school.”
The Defenders received a wealth of encouragement from the boys during their journey.
“The boys were supporting us along the way, and that was exciting to see,” Stevenson said. “It was nice to have their support behind us, and we give them our support, too.”
Tri-unity’s squad consisted of only 10 players: six juniors and a pair of sophomores joined the lone seniors.
After enduring two one-point losses on buzzer-beaters early in the season, as well as double-digit losses to Fruitport Calvary Christian and Grand Rapids Covenant Christian, the Defenders began to find their groove.
They gained confidence with each victory and built momentum for the postseason.
“The middle of the season we started coming together and playing as a team,” Sinner said. “I could see some special things happening. There was this determination and this commitment to going out there and leaving it all on the floor. You could see it in their eyes.”
Junior guard Cierra Smith provided a spark for Tri-unity, as did 6-foot sophomore Elasia Craig, who averaged 12 rebounds a game and set a school record for blocked shots with 82.
A demanding schedule, which included games against Class A, B and C squads, also factored into the Defenders’ success.
“Playing those schools helped us prepare and get ready for these months,” Sinner said. “I don’t think we’ve done that in the past, but we’re trying to do that now. I would rather take my lumps during the season in order to prepare us for this time in the season.”
The future of the girls program remains bright with the graduation of only Buffum and Stevenson. An experienced core will be back and a group of younger players are waiting in the wings.
“I have five freshmen playing now, and seven eighth-graders and 13 seventh-graders who are coming to these games and seeing the excitement,” Sinner said. “Hopefully it keeps growing this way.”

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.
