So many great responses here. I have to agree with the Cowherd nomination - he is a douche. Then someone mentioned Dr. Z in passing, and he is also a douche. Yet to be nominated in the broadcasting category, but eminently deserving, are Tim McCarver and Bryant Gumbel. Can we include the entire Fox football pre-game team, Bradshaw in particular? How about that hockey dude with the mullet? Marv Albert?
And is there an animated category? I hereby submit Scooter, the talking baseball.
As for players, coaches, agents, and the like, there are just too many to choose from. T.O. is a douche, albeit a benign and stupid one, more of a douchie puppet than an actual douche puppeteer. For that, we have to turn to T.O.'s ventriloquist, Drew Rosenhaus. You've gotta put A-Rod and Drew Boras in their class.
For crime, we have Pacman, we have OJ, we have the Baltimore Ravens (Jamaal Lewis, Ray Lewis), Mike Vick, gosh, so many more I could mention.
Coaches category - Belichick, Bob Knight, Rich Rodriguez is sticking in my craw right now. I'm in no way related to West Virginia and I have no interest in college football, but this guy is dicking over the taxpaying residents of that state for $4 mil. Pat Riley. Bobby Petrino.
I look forward to the continued nominations.
