They seem to be getting more comfortable (I listened to a couple pre-season games and they were shaky at first).
One thing I like is AVP's knowledge of the X's & O's. He gives lots of detail including, for example, which guard made which key block, or missed which assignment, etc... He really knows, of course, the NFL playbook and this gives the listener a deeper understanding I think.
I think they will become a very good team. The only thing that takes some getting used to is that AVP does not have a strong radio voice (or delivery). It kind of sounds like some guy you know got to be on the radio.
