I actually think Rush being on NFL Countdown is going to work well. Most of these pre-game shows are entertainment and opinion-driven shows. Whether you agree with him or not (I admit that I do more often than not), no one is more opinionated than El Rushbo. Plus, even if he fails, he has a radio show with 22 million listeners to go back to and a $285 million contract to boot.
Limbaugh may be a blowhole at times, but so is Berman.
