Northwest Missouri State University head football coach John McMenamin has announced the addition of two new assistant coaches and the retention of four others for his 2025 coaching staff.

Collin Prosser – Offensive Coordinator/Offensive Line
Prosser joins the Bearcats after serving three seasons as the offensive coordinator and offensive line coach at Wayne State College. Prosser also worked five seasons at Minnesota State where he served as offensive coordinator/quarterbacks coach for two seasons and offensive line coach for three years. Prosser spent two seasons at the University of South Dakota where he coached special teams, offensive line and defensive line. Prosser coached four seasons at Morningside College following work as a graduate assistant coach at South Dakota. Prosser played at Wayne State from 2005 to 2008 where he helped the Wildcats to a berth into the NCAA Div. II playoffs in 2008 as a team captain.

"Coach Prosser is a masterful technician who demonstrates an exceptional commitment to developing student-athletes," McMenamin said. "His extensive experience in leading some of the nation's top offenses will be an invaluable asset to the Bearcats."

Jake Willrich – Special Teams Coordinator/Defensive Backs
Willrich served as an assistant coach at Wayne State College in 2024. The Wildcats ranked No. 3 in the country in net punting (41.94 yards/punt) and No. 6 in the nation in kick return coverage (14.53 yards/kick return). Willrich is no stranger to Northwest or the MIAA having been a graduate assistant coach at Northwest in 2003 and 2004 and was an assistant coach at the University of Nebraska-Kearney from 2014-2022. Willrich spent five seasons at Austin College (NCAA Div. III) as defensive coordinator, secondary coach and strength & conditioning coach. He also gained coaching experience at Hastings College where he was a part of a turnaround of a program that culminated with a berth into the 2009 NAIA playoffs. Willrich played college football at Truman State University.

"Coach Willrich brings extensive experience coaching special teams and the secondary in the MIAA, consistently producing some of the nation's top-performing units," McMenamin said. "With 18 years of experience coaching defensive backs, his ability to connect with student-athletes sets him apart as one of the best in the field."

Chad Bostwick – Defensive Coordinator/Linebackers
Bostwick was retained by McMenamin and will serve as the defensive coordinator and linebackers coach for the Bearcats. Bostwick will be entering his 15th season as a Bearcat assistant coach having joined the program in 2011. He was an all-MIAA linebacker at Northwest when he played from 2001 to 2004. Bostwick has coached 12 first-team all-MIAA linebackers in Carter Edwards (2024), Jackson Barnes (2021), Ben Althoff (2017), Jacob Vollstedt (2015, 2016), Brock Sherman (2015), D.J. Gnader (2013, 2014), Eric Reimer (2013, 2014), Collin DeBuysere (2012) and Chad Kilgore (2011).

"Coach Bostwick exemplifies what it means to be a Bearcat," McMenamin said. "His passion for the game and profound understanding of building and elevating an elite defense are unparalleled. With experience coaching and winning multiple national championships, he knows exactly what it takes to shape a championship-caliber defense. He leads with the same unwavering dedication and relentless pursuit of excellence that defined his playing career here."

Ryan Gent – Recruiting Coordinator/Wide Receivers
Gent will serve as the recruiting coordinator and wide receivers coach for the Bearcats. Northwest wide receiver Luke Mathews led the MIAA in yards per catch (19.13) in 2024 and earned second-team all-MIAA honors. Gent served as offensive coordinator and wide receivers coach at South Dakota Mines for former Bearcat assistant coach Charlie Flohr from 2020 to 2023. Gent was a wide receivers coach at Abilene Christian from 2017-2019. Gent was a graduate assistant coach at Northwest in 2014 and 2015 before ascending to running backs/tight ends coach for the Bearcats in 2016. Gent was a part of two national championships at Northwest in 2015 and 2016. Gent was a quarterback at Iowa State University from 2010 to 2013.

"Coach Gent epitomizes mastery of his craft, consistently developing some of the nation's top wide receivers," McMenamin said. "His exceptional ability to communicate and bring out the best in his players is evident every time you watch his group in action. With a wealth of experience, he will play a key role in shaping our game plans each week."

Roberto Davis – Defensive Line
Davis will move to defensive line coach after serving as the running backs coach at Northwest since 2021. Davis coached a trio of first-team all-MIAA running backs in Al McKeller (2021), Jamar Moya (2022) and Jay Harris (2023). It will mark the second tenure under head coach John McMenamin for Davis as he joined the Wayne State staff in 2020. Davis was a graduate assistant coach at Northwest in 2019 a year that saw the Bearcats win the MIAA title and reach the NCAA Div. II playoff quarterfinals. Davis played two seasons at Northwest in 2009 and 2010, where he helped the Bearcats to a national championship as a junior.

"Coach Davis is a true Bearcat at heart," McMenamin said. "From his journey as one of the best defensive linemen in Bearcat history to now coaching the same position, he is poised to elevate this unit to new heights. His unwavering commitment to building strong relationships matches his passion for success, making him an invaluable asset to our program."

JMychal Grau – Director of Equipment Operations/Tight Ends
Grau will continue in his role as Director of Equipment Operations and Tight Ends Coach. Grau joined the Bearcat coaching staff in 2022 as a graduate assistant coach working primarily with the offensive line and tight ends. Prior to Northwest, Grau worked as a quality control assistant coach at the University of Northern Iowa.

"JMychal Grau has excelled in coaching the tight ends at Northwest, bringing a tireless work ethic and a relentless drive for improvement," McMenamin said. "In addition to his coaching success, he has elevated our operations to new heights, solidifying our status as one of Adidas's flagship programs for equipment and apparel."
