Tyrann Mathieu turned in an MVP performance when the No. 1 Tigers needed him most. He ran back a punt 62 yards for a touchdown, set up another score with a fumble recovery and finally finished off Georgia (No. 14 BCS, No. 12 AP) with his best play yet -- a whirling dervish of a return that led to the decisive TD in a 42-10 victory in the Southeastern Conference title game Saturday.
