College football star AJ McCarron has made a name for himself on the gridiron, leading the University of Alabama to BCS national championship victories the last two seasons. Last May, the Crimson Tide quarterback joined former Daytona 500 champ Michael Waltrip as a special guest at Talladega Superspeedway, nearly two hours east of the Tuscaloosa campus. Waltrip drove a No. 55 Toyota paint scheme commemorating Alabama's repeat national titles, and McCarron was the ceremonial pace car driver to start the Aaron's 499.
