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.

MCC's Glover Fills Key Role as Athletic Trainer for Super Bowl Champions

David Glover never had the glamour role – and didn’t even play the glamour sport – during his high school days at Muskegon Catholic Central.
MCC is known statewide as a football powerhouse that ranks third in state history with 12 MHSAA Finals championships during the playoff era. But basketball was Glover’s sport of choice, and his specialty didn’t show up in the box score.
“I was the defensive stopper,” explained Glover, who graduated from MCC in 1996. “I was always the guy that Coach (Greg) Earnest would put on the other team’s best scorer. I took a lot of pride in that.”
Glover continues to be the ultimate team player, only now his role is the first assistant athletic trainer for the Kansas City Chiefs, who are aiming to three-peat this season as Super Bowl champions.
“As the team and the goals have grown, so have I,” said Glover, who has been on the Chiefs’ training staff for the past 18 years. “The job is the same, which is getting the players onto the field and back onto the field after injuries so that they can perform at their highest level. I have become more comfortable and experienced in that role.”
Glover broke into the NFL as an athletic training intern with the New York Jets in 2004. He came to Kansas City in 2006 when Jets head coach Herman Edwards took the KC job, bringing Glover and several other members of the training staff with him.
Glover quickly fell in love with the Chiefs’ famous family-first culture, along with the area’s world-famous barbecues. He also met his future wife, Jera.
He is known as a tireless worker and student of his craft, which has allowed him to steadily move up to his current position as first assistant athletic trainer on the Chiefs’ five-member training staff, second only to Rick Burkholder, the vice president of sports medicine and performance.
Glover’s skills also have caught the attention of his colleagues across the NFL, who awarded him the 2022 Tim Davey AFC Assistant Athletic Trainer of the Year Award – given annually to someone who represents an unyielding commitment, dedication and integrity in the profession of athletic training.
Glover said a big reason for his success in his profession can be traced back to high school.
“Playing sports at MCC, especially for a smaller school, gave me such a sense of camaraderie, teamwork and a family outside of my normal family,” said Glover, the son of David and Lyndah Glover. “Those teammates energized me to be my best.
“There’s no doubt that some of the lessons that I learned playing sports in high school help me out in my job.”
Glover also ran track for the Crusaders – competing in the long jump, 200 meters, 400 meters and various relays – and said he enjoyed himself, even though he ran track initially as a way to stay in shape for basketball.
The highlight of his MCC basketball career came his senior year, when the underdog Crusaders captured a Class C District championship.
Growing up in Muskegon and close to Lake Michigan, Glover thought he would become a marine biologist someday – that is, until he suffered an injury during his senior basketball season.
Glover went up for a block and actually pinned the opponent’s shot against the backboard. However, the shooter inadvertently took his legs out on the play, causing him to crash violently to the court and lose feeling in his right leg for about 10 seconds.
The injury to his hip flexor put him on crutches for two weeks and off the court total for about a month, which he said “felt like the end of the world” at the time.
But the injury led him into rehab with Brian Hanks, a 1988 MCC graduate who was back working at his alma mater as an athletic trainer through Mercy Hospital.
Glover and Hanks turned out to be a perfect match. Glover was naturally curious about the entire process and wanted to know the “why” of his rebab program. Hanks recognized Glover’s interest in how the human body works and encouraged him to consider studying athletic training in college.
“God works in mysterious ways,” said Glover. “I was devastated when I got injured, but that experience opened my eyes to a whole new career. I wanted to learn everything I could about the human body and how it works.
“Looking back, the injury was a blessing in disguise. I wouldn’t change anything at all.”
Glover followed in Hanks’ footsteps and attended Central Michigan University, spending countless hours in the training room working with athletes in every sport – from football to track to gymnastics – graduating with a degree in health fitness and exercise science.
He said a huge inspiration in his career was CMU professor Dr. Rene Shingles, who in 2018 became the first African-American woman to be inducted into the National Athletic Trainers Association Hall of Fame. Shingles encouraged Glover to continue his studies at Seton Hall University in New Jersey, where he earned his master’s of science in athletic training.
He got his break into the NFL with his internship with the Jets, and his work ethic has kept him there for the past 20 years.
“If there are high school kids out there reading this, I guess I would tell them that there are a lot of different avenues to get to the NFL or the NBA,” Glover said. “I’m a perfect example. I didn’t even play high school football, but through athletic training I have been part of three Super Bowls.”
The Chiefs, who won their first Super Bowl way back in 1970, would have to wait 50 years (until 2020) to win their next one. But Kansas City now has won three Super Bowls in five years, adding titles in 2023 and 2024.
“To have these kind of experiences, and to be able to share so much of it with my family, is really a dream come true,” said Glover, 45, who said his ultimate goal is to become the head athletic trainer for an NFL team.
“I am always open to see what opportunities God has for me and what doors he opens.”
More immediately, with the start of training camp last month, Glover is back to his seven-day-a-week schedule, sharing the organization’s goal of making it to the Super Bowl for the third consecutive season.
Glover has worked with all of the Chiefs star players at some point, including star quarterback Patrick Mahomes, who he calls “a great, humble man.”
But perhaps the player he has worked with most is standout tight end Travis Kelce.
Kelce, who has become a huge name outside of football as the boyfriend of pop sensation Taylor Swift, injured his knee during his rookie preseason in 2013, sidelining him for the entire year. Glover was assigned to Kelce for his rehab.
With Glover’s daily help, Kelce was able to get back on the field the following year and emerged as a star, earning him the 2014 NFL Ed Block Courage Award as a model of inspiration, sportsmanship and courage.
After winning the award, Kelce invited Glover (he calls him “DG”) and his wife to attend the award ceremony with him in Baltimore.
“That was a huge honor for me, and I was blown away,” said Glover. “I look at it that I was just doing my job. He entrusted and believed in me throughout the process, and it worked out great.”
