Tim Sylvia by far!
He has had several boring fights, blames it all on a back injury, has surgery for it and claims to be 100% again and yet he is still just as boring as before! This alone puts him at the top of the list... if you then add his dumb-ass statements that have surfaced recently he is easily #1 on the douchebag list.
And you know what's worse? History tells us that he's not going to get any better
