I don't miss Hudler or Physioc at all. Hudler was a complete homer, and both of them would say downright idiotic things far too often. Couldn't stand listening to either one of those guys.
I really enjoy Rojas, I think he calls the game pretty fairly and is not afraid to call out players or managers. As for Gubicza, sometimes he can get repetitive, and I don't really care for his "song title as a key to the game" silliness, but other than that he's fine. I wouldn't trade him for Salmon, since Salmon is too much of a homer.
