New head coach Billy Cosh looks to bring change to SBU football

By Kenny Spurrell

After the removal of former head coach Chuck Priore in Nov. 2023, the Stony Brook football team has found his replacement in hopes that brighter days are ahead.

Finishing the 2023 season with an 0-10 record — the worst in program history — was not the way the Seawolves hoped to bounce back from 2022 that ended with a 2-9 finish. Just under a month after removing Priore, Stony Brook hired former Western Michigan University offensive coordinator and quarterbacks coach Billy Cosh to fill the role.

Cosh, 32, a resident of Smithtown, started his coaching career at Concord University in 2015, soon getting the position as a graduate assistant and quarterbacks coach for Indiana from 2016 to 2017. Cosh made the move to the Virginia Military Institute in 2018, serving as the wide receivers coach in 2018 and 2019, then getting promoted to offensive coordinator and quarterbacks coach for the 2020 and 2021 seasons.

Cosh jumped to Richmond in 2022 where he led a top 20 offensive SP+ rating, advancing to the second round of the FCS playoffs in his lone season. After serving as offensive coordinator at Western Michigan for the 2023 season, Cosh was named the third head football coach in Stony Brook history. At 31 years old, he became the second-youngest current head coach in NCAA Division I football.

Coaching at Richmond in the Coastal Athletic Association (CAA) — the same conference as the Seawolves — Cosh said he has “always admired Stony Brook from afar.” In his first head coaching position, Cosh will look to pull the Seawolves out of the cellar.

“I knew this place has a chance,” Cosh said. “I knew they had the capability, so that’s kind of what attracted me to the job.”

Football is in Cosh’s blood. Bouncing around from place to place during his upbringing, he is the son of Chris Cosh who played linebacker for Virginia Tech from 1977 to 1981. Chris coached for 40 years at multiple FCS schools such as UNLV, Maryland, Michigan State, South Carolina and many more. He currently serves as an analyst at Western Michigan.

“I thought my dad had the coolest job in the world,” Cosh said. “I was like a sponge; I was around the game all the time. I got to see different players that played in the NFL and watched how they work and watched how coaches coached, it was really unique.”

Cosh was raised with his brother, James, who went on to play football at the United States Naval Academy from 2007 to 2011. James is currently a scout for the Chicago Bears in the NFL.

Being brought up around football, Cosh was destined to be a star on the field. Attending Arundel High School in Gambrills, Md. from 2006 to 2009, Cosh won the job of starting quarterback his junior year. He went on to break seven state records that season including most passing yards (3,909) and touchdowns (56), but it paled in comparison to his senior season.

Cosh’s senior year was special, throwing for 3,913 yards and 56 touchdowns. He set Maryland state records for career completions (594), passing yards (7,433) and touchdowns (112), finishing his high school career with a 22-3 record and leaving college coaches clamoring to have him on their team.

Though Cosh’s achievements on the field spoke for themselves, he credits playing with future NFL wide receivers RJ Harris and Alec Lemon for much of his success at Arundel.

“That kind of made a big difference,” Cosh said. “I wasn’t a great player, but I was very appreciative of the guys around me.”

When the college recruitment process came around, the choice was rather simple for Cosh. At the time, his father was the defensive coordinator at Kansas State University. A chance to play at a Big 12 school and have his father guide the way was too good for Cosh to pass on, deciding to play college football as a Wildcat.

Unfortunately, when things seem too good to be true, they often are. Cosh’s coaches opted to give him a freshman redshirt his first season at Kansas State, meaning he would be sidelined and not see action the entire season.

Looking ahead to his sophomore season, Cosh realized there may not be an opportunity for him to play anytime soon. With three quarterbacks on the roster that were returning the following season, all of them were ahead of him on the depth chart. He was paid a visit by James Madison University’s head coach Mickey Matthews who told Cosh he would have a better opportunity playing for him, so Cosh made the move.

Transferring to James Madison for his sophomore year hoping that he would have the chance to play, Cosh’s wishes were not answered. Again, Cosh was at the bottom of the depth chart and did not see action the entire season, later claiming that the move from Kansas State was one that he regretted.

“I really made a rash decision to leave, Coach [Bill] Snyder told me I would regret it, and he was right in some ways,” Cosh said. “I went [to James Madison] and was kind of told I wasn’t good enough, which was probably true, I wasn’t the greatest player, but I was never really given a shot.”

Cosh realized that he would have to step down a level if he wanted to get any real playing time, opting to transfer again, this time to Butler Community College in the NJCAA. Making the move in hopes to impress scouts and get back to the Division I level, Cosh did just that.

Stepping down a level gave Cosh the opportunity to see the field, but the talent pool in the NJCAA was very deep. He played with “12 to 15” future NFL players and against current All-Pro players such as Tyreek Hill, Alvin Kamara and Cordarrelle Patterson.

Cosh’s lone junior college season was described as a “rebirth” for him by Butler head coach Troy Morrell. He turned heads by throwing for 2,856 yards and 25 touchdowns in 2012, but he would soon face another obstacle. Cosh tore his ACL in the NJCAA junior college championship game and lost to Iowa Western, 27-7.

Despite the sour ending, Cosh reflects on his time at Butler fondly.

“I loved that time,” Cosh said. “I loved my teammates. I loved the coaching staff … so that was awesome.”

Despite the injury, Cosh had impressed college scouts enough to receive some offers. He committed to the University of Houston before the conclusion of the 2012 season, successfully making his way back to the NCAA Division I level.

However, Cosh soon faced another roadblock. His commitment to Houston came before the injury to his knee, something that he thought would lead the team to pulling his scholarship. To Cosh’s surprise, the Cougars chose to keep him around.

Still rehabbing his ACL tear, Cosh missed the entire 2013 season due to injury. He made his debut in 2014, and though he only saw the field three times at Houston, he was able to end his college career on his terms, not others’.

Though Cosh’s time at Houston was underwhelming on the field, it was where he met his wife, Kelsey.

Being around the game of football his entire life, Cosh has faced plenty of adversity throughout his career. Due to these challenges, it makes sense that Stony Brook Athletic Director Shawn Heilbron believes that Cosh is the man for the job to bring the Seawolves back to relevance.
