His passion for football will be contagious throughout our community and will make for a great experience for all."

"I've always had the coach's mentality," he said. "My wife and kids call me 'linebacker man' because I'm always pointing out something, always coaching.
"I've always felt like I've had a gift for teaching and helping kids. Not only helping kids but helping the guys I coached with the Bears. I always felt like I wanted to coach and felt like I'd be a coach at some point. I'm excited."
