It's obviously sad, but not much worse than had he retired. So I am not mad at Tom, it's still a business after all, it will never change. Wish him all the best.
This franchise is now at a crossroads. Are they tanking for a top pick or opt for a quick retooling process when nobody knows how much longer Bill will be coaching. Newton may be available via trade. Prescott? Most QBs in this league suck and we don't have a working running game like (still questionable if a great running game like Tennessee has with Henry is ever going to win you anything again).
Would they want Jimmy back if Tom goes to SanFran? Doubt it. I think he's overrated at this point, his SB-performance was horrible.
