Not that I disagree with this section of your post, I'm just wondering how hardening his heard and heightened determination manifests itself? My guess is by using his proven failing offseason SOP.
I agree completely Jones' standard operational procedure will remain unchanged. He can shuffle his front office personnel around but he has been doing that decades. His replacing himself as GM would be the only tangible change in his usual SOP.
I don't believe Jerry is capable of feeling embarrassment. How many times have our division rivals made it to the championship game and super bowl this century? This isn't just bad luck, it's bad management.
I do not believe it either. Jones does get flustered. Emotion is clearly visible all over his face whenever the team loses or someone throws an unwanted question at him. Episodes of embarrassment? That is rare.
Emphasis on: "This isn't just bad luck, it's bad management." Many on the outside looking in understand a true shake up in top management (a common practice in every form of business) might change the franchise's trajectory for the better through fresh and innovative perspective.
On the other hand, Jones only sees bad luck. For him, trial-and-erroring for 30 years is not bad management. It is bad luck in that, the coaching and player acquisition he has endorsed as smart moves, have never successfully combined into actual championship contending teams.
It is not his fault that his football intelligent actions have not rendered postseason divisional, conference championship or Super Bowl wins (or even appearances for the latter two).
Everyone else is to blame. He bought the team to play GM. He had zero intention of simply writing checks. 'His' expertise won three Super Bowls. He cannot help it if coaches and players have not repeated the same feat since he has won league championships.
His formula worked before, so it should have continued working ever since. After all, 500 owner GMs could not ever do what he has done in a million years.
