Probably because somewhere I read by Gantt or Sorenson (someone locally who professed knowledge of the system) that Richardson wasn't going to retain him because they didn't want to pay him what he was asking money wise for an extension. And no I don't have time to search for a link or argue back and forth. But from what I have read, consistent winning was an issue but money also factored into it as well. He could easily get a coordinator like McDermott for 2 or 3 million a year just like they started out with Fox.
I read that too, but they've also said that Richardson wasn't going to re-sign him because he has never won two years in a row. And now it's that Richardson might re-sign him, but Fox won't sign anyway. They just don't know, but they have to fill inches.
The money thing generally flies in the face of franchise history, particularly where coaching speculation is concerned. I can see not wanting to pay a single guy $20 million for a season, but if the right coach is available, I really believe Jerry will pay what it takes to get him.
With that said, the odds are we go coordinator, which means we won't be paying a ton anyway. When it happens, watch the local press use that as "evidence" of tight pockets...
