My final verdict: It isn't just one thing, one event or one person to blame.
To elaborate further (LONG - so feel free to stop reading) the tipping point was when Sloan wanted to discipline (not necessarily suspend) Deron after the Bulls game for insubordination (not running a called play) and neither Kevin O'Connor nor Greg Miller would support Sloan's decision.
At that point Jerry realized for the first time since the early 90's, he no longer had sufficient support from ownership and management. He learned from his Chicago days (Reggie Theus) what happens when players realize they have more power than the coach and understood he couldn't do his job with one hand tied behind his back, so he resigned - and Phil Johnson resigned with him out of principle.
The NBA was always a players' league - just not to the extent it is now and certainly not with the Jazz. With recent events - the LeBron Decision, Melo, CP3/Dwight/Deron 2012 speculation and the Cavs historical losing streak - owners and general managers are scared more than ever of losing their superstars.
Because it's easier to get rid of the coach than the layers, if players don't like a coach they'll often quit on him and wait him out until he gets fired. Larry Miller understood the key to successful coaching was ensuring the coaching staff had enough support and job security so the players would be forced to buy into the coach's system.
With Larry's death and the recent events around the league, Utah's new ownership and management have deviated from that philosophy.
In no way shape or form did Deron force Jerry out. With that said, the company-line that this was solely Jerry deciding on his own to step down because he was worn out is also a bunch of B.S. If you believe
that - I think you could be sold any bill of goods in the world. The franchise is hoping that - like Santa Claus - fans will want to believe the best about the organization rather look at things with common-sense, hence O'Connor's national media tour on Friday. Unfortunately for KOC, it took 10 minutes of bad grammar for Karl Malone to un-do alot of what he was trying to stress.
I don't blame Deron because unlike some disgruntled superstars - he isn't confrontational because he wants numbers, fame, or a big market. He just wants to win, and I respect the heck out of him for that. While I will agree he needs to improve his leadership - for the franchise leadership has to start at the top, and that's the area that has sorely been lacking through this whole situation. And it's the two men at the top of this organization that I blame more than anything.
