27 seasons without getting to the championship game, let alone the Superbowl. Jerry is ultimately the problem. Jimmy was the man who brought the team to greatness. Jerry is the one who wanted to take credit.
As for hiring a new coach? No more retreads. And no more meddling in day-to-day football affairs Jerry. Pay the bills and leave the coaching to someone who knows how to win.
You said it all in a nutshell, Jerry wants to take credit. That's the core issue with this organization.
He doesn't want another Jimmy, which is why we get these "yes" men the last 25 years. Parcells was the lone exception.
Look at other owners, they hire football professionals, and let them manage, but Jerry just can't do that.
Personally, I'd like us to go in one of 2 directions.
Either get a proven guy, like Belichick or Tomlin, whio will change the culture, or get a young mind like McVay/ShannahanRyan type and rebuild.
Mu guess is Jerry will talk loudly about how unhappy he is and that changes are coming, then MM will be back, and we will do the same thing next year.
