Bob made similar remarks about the joint broadcasts during the STH picnic last year too. He didn't like the fact that it was Jim Hunter who got to call Strasburg's home run, and I can't blame him. These remarks were made during informal conversations with fans, not as part of the formal Q&A sessions. Still, he is very gracious in interacting with fans (and giving his honest opinions), posing for pictures, signing autographs, etc. Given how many personalities have a big ego and can be total pricks, Bob is as nice as can be.
