I honestly think this makes it even more likely that Deron leaves when his time is up. We'll have to see how it plays out over time, but I think it's entirely possibly that the tension between Deron and Jerry will used as the reason Jerry left- at least that's how history will remember it. With that being said, a large amount of Jazz fans are going to feel uneasy about Williams and the fact that his attitude may have indeed ran Jerry out of town. I think Deron will grow weary rather quickly of having a "coach killer" label here in Utah and he'll get out of here the first chance he gets.
Utah shouldn't look to trade D-Will at all costs but they should start entertaining serious offers. If a windfall of decent players/prime draft picks can somehow come out of it, they should look hard at it. In all honesty, looking back over the last year or so I think we've started to see a side of D-Will that makes me think he'll spend his career not playing nice with others if he doesn't get his way. And while I may love D-Will, team after team has shown us that you win NBA titles with talented atheletes, great front courts, and and merely decent PG play.
