Redskins running back (and borderline loon) Clinton Portis has entertained many in the DC area with his various costumes that he wears to press conferences. Portis has certain personalities that he likes to showcase and when you consider the alternative – a-holes who don’t want to talk – this is kind of refreshing. (Here is some more history on Portis' costumes.)
Portis was on the set of NFL Network's Total Access (don’t worry, nobody else gets that channel either) debuting four new characters. Fans can vote for their favorite on NFL.com.
My personal favorite is Bud Foxx. Be sure to vote.
