I have to say it's a toss up between Jim Gray, and Larry Merchant. But I think Gray takes it. Yes, Merchant can be rather "controversial" at times, it's almost more humorous rather than rude and/or disrespectful, mainly due to the fact Larry is so old now. Gray though, is a down right ******* at times, and rather balsy. I mean he'll look you straight in the eye and tell you to shut up, or call you a liar haha. The one good thing about Gray's personality and demeanor is he's not afraid to ask the questions that need to be answered.
