I can't count how many times they called the Pats the Bills and vice versa, Todd Light, etc. They sound like a trio doing a high school football game in Rochester.
Razor's have you looked into a DVR? What I do is I use my DVR and the Internet radio and synch it up by pausing the DVR and restarting it at the appropriate time when the game starts and then just go from there. Sometimes it takes a little while to get the timing exact, but it's worth it not to have to listen to such terrible announcers. I only do that when there are announcers I don't like on.
What is the facination with Gil and Gino? I remember I had to listen to one of the preseason games in the car for the first series. Welker was apparently having a hell of a game according to Gil and Gino. When I made it into the house and turned on the TV I saw Welker sitting on the side lines in street clothes. That was a quick switch.
The only good think about listening to the local broadcast is that it is always more homer centric. Sometimes you don't care about the other teams prespective, especially when your team is losing. But other then that, I think the national announcers are much better.
