Further, if guys like Jackson, Thibs, Vogel, etc. open up, and the Pels don't even take the time to look into it, that is a massive failure on their part.
One of these things is not like the other...
Thibs is great, but his big problem has been trusting the subs late in the game. Forcing Rose to play too many minutes got them to where they are know thanks to him blowing out a knee in garbage time. That is something he can learn from, though.
Vogel's suffering from locker room issues that were in part foisted on him by management, thanks to sending out Danny Granger while bringing in Andrew Bynum and Evan Turner.
Turner's getting into fistfights with the volatile Lance Stephenson while a bunch of people are claiming that Bynum's gotten into the head of Roy Hibbert, contributing to his total collapse in on-court performance.
Stuff like this is hard for even a great coach to overcome if his hands are tied.
Jackson's a great player's coach but his handling of his assistants and management are a big WTF. That indicates maturity issues that could be fixed but I'm not sure if we'd want to take the risk given that three of his top assistants have been fired, re-assigned, or left for other jobs since the end of last season because of friction with him.
I see him as more high-risk than Vogel or Thibs by far.
