Jerry also dished out the money to sign the players and coaches that Jimmy wanted..Jimmy went to Miami, the owner didn't want to spend the money and what happened. Even Marino couldn't help him.
Coaching is a team effort. A HC can't do it all by himself.
Pretty much every owner that has won a SB has dished out the money to sign players and coaches.
The difference here is that most other owners understand their limitations and hire people to help them win a SB. Jerry and his son have decided their football knowledge is vast enough that they don't need a GM to handle the football operations. They had that in Jimmy, as he was part GM and the HC.
But Jerry was jealous of the hype Jimmy got and credit bestowed on him for those 90s teams. Hiring Barry Switzer was the first step in Jerry trying to prove to everyone he was the guy, not Jimmy. But once those Jimmy Johnson teams fell apart due to age, introduction of the cap, etc. Jerry has basically wandered in purgatory as the mind behind the football operations.
He needs a Jimmy Johnson type - either as a HC who can convince him what to do on personnel or a GM that can handle the day to day operations. And no, McClay isn't that guy. He's just a super scout. What Jerry needs is a guy who is loud enough and forcible enough to tell him he's screwing the pooch and needs to do this instead. Jerry is too insecure to hire that kind of guy.
