ROSEMONT, Ill. (AP) — Ohio State athletic director Gene Smith had high praise for college football's playoff system — and a warning to the NCAA about adding another round. More bandages will be needed. Smith said his Buckeyes were a banged-up bunch as they marched toward the championship and expanding the playoff field form four to eight teams will only add to the bumps and bruises. Ohio State knocked off Alabama in the Sugar Bowl and Oregon in the title game.
