I don't follow sports, but I generally find the sportscasters to be loud-mouthed and obnoxious. That said, I have worked with a few sports people in my time (Kyle Rote, Jack Whitaker and Frank Gifford come to mind) and they were all nice guys. I think Bob Costas is a good interviewer and I used to enjoy his non-sports interview show. I also worked with John Facenda, who was the Cronkite of Philly (without he brain) and, I understand, a sports voice (football?). He was also a nice guy, but somewhat full of himself and clearly in his position due solely to a good radio voice.
