Don't mess with Rose Bowl tradition. Organizers decided to stick with their historical Pac-10-Big Ten matchup Sunday, picking 13th-ranked Illinois to play USC on New Year's Day after Ohio State got upgraded to the national championship game. "Illinois presented the tradition of the Big Ten-Pac-10, and wanting to stick with that tradition when we can was really the primary decision," said CL Keedy, president of the Tournament of Roses Association.
