Nope. Anyone who believes that should go back and watch all his end of the season interviews. I was completely convinced he'd be back before that, but everything he said, the way he said things, and his body language as well, made it pretty obvious he was on his way out.
Somebody else was talking about this, and the thing that really rang true with me, was when they tried to get him to talk about the team or the future, he went cold. When they asked him about the fans chanting his name, he paused for some time, and then said it was really cool and something he'd take with him. Absolutely nothing he did or said indicated he was even considering staying in Utah IMO.
I had no doubts after that, but have tried to ignore my gut feeling and hope he might reconsider. The report leaked out early and that dick had the nerve to say he hadn't decided yet, just so that he could make the announcement with his pathetic thank you letter. Dude is a chump who doesn't deserve any benefit of the doubt, whatsoever.
