2025 Offensive Outlook: We’re looking to pick up right where we left off last season with a strong returning core and new talent ready to step up. Four key offensive linemen are back—Kevin Cloak, Sam Maulbah, Dameon Reese, and Luke Serino—providing experience and toughness in the trenches. Jack Costelo joins the group as our new center, solidifying the line.

At quarterback, Mason Boyer returns to lead the offense, supported by reliable wideouts Maddox Jarzynski and Caleb Klepeiss. With David Odubo, Keyon Nimmons, Anthony Brown and Mason Noecker also ready to contribute, we have a deep and versatile group of pass catchers ready to make plays.

In the backfield, we have a strong, physical trio that runs with purpose. Senior Adonis Sutton, sophomore Brandon Harris, and freshman Sean Atkins each bring a different skill set to keep opposing defenses on their heels.

At tight end, we have a versatile group that can block and stretch the field—Marcus Yeage, Sam Sweppenhiser, and Adam Dalton all bring different strengths to the position and create matchup problems for opposing defenses.

With this foundation, we’re excited about the direction we’re heading and confident in the team’s potential this season.

2025 Defensive Outlook: Our defense is anchored by a dominant defensive line featuring Sam Mulbah, Dameon Reese, Marcus Yeager, Adam Dalton, Luke Serino, and Sam Sweppenhiser. This group is relentless and will do whatever it takes to shut down any opponent. The linebacker corps is led by sophomore Brandon Harris and includes a versatile mix of talent with Broady Dunlap, Maddox Jarzynski, Caleb Klepeiss, Adonis Sutton, and Shane Dunlap. In the secondary, we’re loaded with athleticism and depth, with Gavin Mann, David Odubo, Keyon Nimmons, and Sean Atkins ready to make plays all over the field.
