First, Newman is coming back and Pacman is still an option. The team certainly thinks so as long as it continues to pay $20,000 per week to keep him on the roster.
Second, The media would rip Jerry for it and he wouldn't like that.
Third, I think even Jerry knows when too many ego's is overkill. He also knows the the talent doesn't match up to the ego. This guy is basically a bum now.
He's lost his confidence. He's getting burnt multiple times a game. A bunch of other teams are already interested on wasting money on him.
