The Atlanta-born, Stanford grad was drafted as a running back by the Oakland Raiders after finishing college. He was eventually released and moved to LA, where he was bitten by the acting bug and booked numerous national commercial and print campaigns before landing the “Madea” gig.

By comparison, CBS’ “Person of Interest” averaged 5.32 million viewers for second place, followed by ABC’s “Celebrity Wife Swap” pulling just 3.375 million viewers, according to Nielsen.
