Who do you WANT to replace John Madden?
I've seen some message boards discussing who would be a good long-term replacement.
Chris Collingsworth doesn't cut if for me.
He has no skins on the wall and he's not particularly funny or interesting.
Here's my list: if you think I'm missing somebody, post a comment!
Actually, I think Bill Parcells would be a great choice eventually.
He knows many of the coaches personally and can speak to experience at all levels (GM, Coach, Draft).
He's funny, says interesting things, and is a fountain of football wisdom.
He is quite adept at breaking down game film and strategy.
He also has skins on the wall and has coached and has experience with many many teams.
