I just recently came across a Facebook / Wikipedia page for the actor who plays Triple T. I had always wondered about him -- it seemed impossible that he hadn't actually played somewhere, and at a high level, but I'd never seen or heard of him. As it turns out, he never made it to the NFL, but he was a Division 1 All-American linebacker in college. [ETA: He also has an official website.]
Andrew Griffiths (Courtney Cate) is a bit more of a mystery. His only other credit on IMDb is an appearance as himself in a documentary about Sting.
