Edit, quote from Dax:
At the end of the day, I totally respect Jesse’s decision to trade me for business reasons, if that’s his reason. If he wants to get guys, younger guys more minutes than I certainly agree with it in terms of trying to make the club better and move the club on. But I told Jesse to his face that I didn’t think the way that he handled it was appropriate and it certainly was a big surprise. I certainly thought the club could’ve gone about it a better way, but that’s life in professional sports. I respect Jesse as a coach. He’s a hell of a coach and I think he’s gonna do great things in his career as a coach — but obviously, as a person and a human being, I feel like things could’ve been handled differently and that’s a big shame.”
That's an unhappy guy making his complaint known in the classiest possible manner.
