I doubt he'll be an instant success or anything, but he's a champion and it wouldn't surprise me if he found a way at some point to place real high at a tourney and make more money than all his pool scores combined.
John Hennigan (sp?) was a good shortstop player, money player who ran out of action, and became an excellent pro poker player seen on tv.
Heres a link about John:

I'm sure Jay H. will say its a hard road to get there, but people thought Moneymaker was a lucky fluke to win the WSOP - he later made a couple hundred grand just placing high at a different tournement in San Jose, CA.
Alex does well under pressure so if he can learn to play the game pretty well, he has a chance.
Of course, us pool fans will secretly root for him to not succeed so we can watch him fade guys like Shane going crazy on him for 2 days and still pull off an incredible win with his talent and heart. Most entertaining guy in pool, IMO.
