Not surprisingly, of the four networks who show NFL games, ESPN has by far the worst tandem.
CBS
Jim Nantz - always great
Tony Romo - really good already and will get better
Fox
Joe Buck - solid, better than he used to be, and has great chemistry Aikman
Troy Aikman - great
NBC
Al Michaels - the best play by play football guy ever
Cris Collinsworth - some are not a fan, but I think he is really good
ESPN
Sean McDonough - he's okay, but doesn't seem nearly as good at football as he was at baseball
Jon Gruden - has gotten better after being awful at first, but still a bit too praise-effusive
