I appreciate the sentiment and generally agree. But, I think we have some pretty decent local announcers here if you can get the local stations. I think Dan DIckerson is great on Tigers play by play. He has a good voice and makes the game easy to follow. Jim Price is a little too much into himself, but he's grown on me. His whole, "nice area" thing is pretty funny. Ken Kal (sp?) and Paul Woods are great on Red Wings games and I can live with Dan Miller for the Lions.
Beckman and Brandstatter are pretty solid Michigan homers. Not quite as good as the few years they had Hanlon on, but they're definitely giving you a maize and blue slant. My issue with them is that they are generally pretty terrible at actually describing what is going on in the game. In the rare, horrible instances when I'm not at the game or able to watch on TV, I hate listening to those guys. Shepard isn't much better for hoops. All in all, UM has good homer announcers, they just need to get better at actually describing the action.
