Just four teams remain in pursuit of a college football national championship. It all gets underway later tonight, when Notre Dame takes on Penn State in the Orange Bowl. The winner of that game will face the winner of Friday night’s Cotton Bowl Classic between Texas and Ohio State.

Ohio State needed to make sure it had enough players to last a grueling, potentially 17-game season. One new addition is the exact reason why.

The main areas of weakness on offense are the Ohio State O-line’s ability to handle extra rushers, ranking 78th with a 9.2% blitz down sack rate, and a somewhat elevated 10.2% blown run block rate that checks in at 94th nationally.
