Greg Mattison decided to chase a few bucks and became a Buckeye. He wanted to be Coordinator and a raise and Ryan Day hired him. Personally, I wouldn't have hired anyone from the squad that my team just put 63 on, but that's just me.
Greg will be brining a bunch of Don Brown's defense to Columbus and he started with Michigan's Viper role that he is now calling the "Bullet". It seems that OSU's defense now calls itself the "Silver Bullets" (Coors Lights for everyone!). There will be a few differences and maybe even some growing pains as they implement a new system.
