FILE - In this Sept. 22, 2012, file photo, Notre Dame's Theo Riddick (6) runs out of the attempted tackle of Michigan's Kenny Demens (25) during the second half of an NCAA college football game in South Bend, Ind. With the national championship on the line, two throwback offenses will slug it out. No. 1 Notre Dame and No. 2 Alabama rely heavily on the run, and that doesn't figure to change in the biggest game of the year. (AP Photo/Darron Cummings, File)
