And the Sunday game suffers because they can't do the same amount of prep/interviews/watch practices that is part of the analysts job. Aikman would only get Fr/Sat to work with the teams and that is not enough time and not enough is going on those two days.
Aikman is too much of a self professed perfectionist to halfway do the Game of the Week and Buck is pretty dependent on Aikman's prep work.
If I were Witten, the fact that it's the TNF game would concern me a bit as that could go away and then he'd have to rely on replacing one of the others, if he'd done a good enough job. I'd wait for a more secure spot like Moose got.
The other part of this is why does Fox think Witten is going to be a lure to bring fans in to watch what was a declining ratings venture for CBS? If they want to use a personality, why not Manning? Enough like him that he might be a pull. I wouldn't watch TNF regardless of who they put in that booth so to me, it's not important but a lot of posters want Witten gone.
Some want Dez gone, some want Witten gone and some want both gone and we do not have the replacement for either on the team, let alone both.
