MIAMI (AP) - Looking for a key to tonight's BCS championship? One might be the performance of Notre Dame's running backs.

Notre Dame tailbacks Theo Riddick and Cierre Wood showed how interchangeable they are in the final two games of the regular season for the Fighting Irish.

Game 11 against Wake Forest, Wood ran for 150 yards, while Riddick had 20.

Game 12 against USC, it was Riddick running for 146 yards, and Wood for 20.

That's been the theme for the Irish this season: Two running backs - and sometimes three - are better than one. That approach has served Notre Dame pretty much since training camp, and the top-ranked Irish (12-0) are hoping it holds true Monday night against No. 2 Alabama (12-1).
