Maybe another owner buys the team, wins the coaching lottery once, and then doesn't proceed to bury the franchise in ego-fueled mediocrity for 20 years. As has been mentioned, it's not like finding Jimmy was some exhaustive search that only Jerry could have pulled off, he hired his drinking buddy.
And you could make the argument that Jerry was also 100% the reason Jimmy left before winning several more rings with the team. Have any other owners in the history of the league chased off winning coaches because they couldn't stand sharing the spotlight?
p.s. I bet there are a whole lotta 20-something year old fans with little or no memory of those Superbowls who would gladly take you up on your world-without-Jerry offer.
