It's always fun trying to psychoanalyse things.
It's an interesting take but I don't buy it.
Although coaching played a big part in Zeke's "decline," I think it was totally silly to pay him what JJ did. Even professional sports writers know that the RB position can be successful with average guys and a good OL!! It was simply another plunger bet by JJ wanting to showboat his ego and have a "star" at RB - even though he's not - and statistics proved this before he was extended.
As far as SJ is concerned, I'm not convinced anything will will be done differently, and I'm not sold on the 2 coaches you mentioned at all. Everyone's been throwing their names around like infatuated girls at the high school prom. On top of that, JJ is about to pay Dak a plunger deal of record money.
I don't care how bloody unlikely it is for Aikman or Romo to work for JJ, but either one of them would be the only thing that un-breaks my apathy and gets me excited for this team's future once again.
After being a fan since the 60s, the last 25 years since Johnson left and especially last 10 years of stupidity, have totally wrecked my ability to care and I know I'm not the only long time fan who's been gutted by this circus. Without a huge Cowboy name as the face of this organisation like Aikman or Romo, in the words of JoDee Messina, "mygiveadarnsbusted."
