When I am listening to a game of a team that I am a fan of I don't care if the announcer is a homer, it is part of his job. I don't care if an sports announcers sees the game from the other side of the coin, I don't need my announcer to give the other team props. Tim Hennesy is one of the best announcers in College hockey, I could care less if he is a homer. As far as the Wild Annoucers I think they are pretty good, in my humble opinion. The Wild announcers are paid by the wild to call the game.
The other night I listened to the Philly announcers as they called the game against the Wild and they were just as bad of homers as you said the Wild ones are. Its just a sports thing. As for the Gophers you have to expect that Woog and Masucko are going to call the game with pro-maroon and gold goggles. If you don't like it just turn down the sound.
