I dunno. I've listened to commentary from other regions, including teams I don't like (had to get out of town feeds in college), and their commentators are a lot more informative. The NY homers don't bother to tell you much about the other teams. If I were a Rags or Isles fan, I'd be pissed, because I would want to know what to look for. Even though Chico's a huge homer (unless the other team's goalie is involved), he also does a good job telling us to watch for on the other team.
I won't pretend to know a lot about other commentators I just know they get a whole lot better and a whole lot worse than any of our areas teams. Specifically I think michaletti howie and cangelosi are above average (compared to the guys I've heard)
Chico is good as a devils fan but what I don't like about him is he's a lot like Jon Gruden who does Monday night football- he only praises players and rarely knocks them. Gruden makes every player out to be a hall of gamer. Chico to a least extent always has positive reinforcement.
Of course all of this is subjective and many guys may like Edwards and the Pittsburgh guys or hate doc or Kenny Albert. There's no right and wrong.
But we can all agree that trautwig is a douche.
