Frank Caliendo looks great on XM radio.
As for TV announcers....I think bigwigs take it for granted that the average joe that watches their games doesn't know diddly about the rules of the game, so any explanation they throw out there will be just fine. Sure would be nice it we could get some knowlegeable umpires on that "color commentary" job - at least for playoffs....
I'm available....and I look great on the radio, too....
