Time and change, right? It's right there in the freakin' fight song. One day you're sitting on your couch with your dog named Brutus while wearing a commemorative 2011 Sugar Bowl sweatshirt as you enjoy your 93rd viewing of the 2015 National Championship game and counting Urban Meyer's nose hairs, and the next you're doing the same thing, but holy crap Ryan Day is the coach and everything is different!
Seriously, everything is different. In the past 72 hours or so, Ohio State's new head football coach has put his personal stamp on the coaching staff in a major way, which is awesome in theory, possibly crazy in practice, but pretty fascinating to watch either way.
