I have never run across one, either. NFL radio is pretty good for the most part, but not geared to New England in any way.
Just as an aside, I've always been amazed at how a syndicated network like that allows callers on the air who are complete idiots. Guys that would never pass screening on New York or Boston sports talk shows get to broadcast their nonsense to a national audience. I don't get it, but there is a certain trainwreck quality to some of those calls.
I conclude that sports talk must be much different that what we are used to in other parts of the country.
