A running back who used to be a wide receiver. A tight end that can split out wide. Notre Dame's offense can change packages without changing personnel. But Crimson Tide linebacker C.J. Mosley isn't worried because he thinks his defense is just as - if not more - versatile.

"We're going to line the right people up with the personnel," said Mosley. "They're going to try to make mismatches. We're going to do our best to scheme up and put our players in the right position."

Mosley, an inside linebacker, most often plays in nickel and dime packages, when the offense has a high number of pass-catchers on the field. The junior may get more playing time in the title game, with running back Theo Riddick and tight end Tyler Eifert both capable of making big plays in the passing game.

The BCS title game is a matchup of the two best defenses in the nation, with each team allowing fewer than 11 points per game.
