College rivalries just don't go away once you leave school. That's true in the NFL, too. New Orleans Saints running back Alvin Kamara and defensive back Tyrann Mathieu were on opposite sides of one last weekend.
Kamara played for the Tennessee Volunteers and Mathieu was a Heisman finalist for the LSU Tigers. LSU was on the wrong end of a 40-13 loss to the Vols, who are now ranked No. 6 in the AP poll.
Mathieu seems to have lost a bet and had to wear orange Tennessee gear at the Saints facility on Wednesday.
