One of the reasons I love the Gobert pick is that I've been worried about Favors and what it might take to keep him. He seems to have gotten worse offensively and if he's going to get the big bucks, then he'd better be able to do something offensively. He's past year 3 and I have only seen incremental growth from him. This year is make or break for him, and there's a good chance that if he carries over what he has been doing to a bigger role that some team is going to throw some ridiculous offer at him and the Jazz will have a really hard choice to make. Gobert could give them a backup plan if the Jazz are forced to be shrewd (which if I know anything, it's that in order to be a champion, you can't afford bad deals, especially not huge deals that are bad).
I'd rather Favors finally be able to score in some way that is reliable, and being the **** rid of Al and getting a PnR PG back could be huge for him. If after four years (and remember, most players are largely what they are going to be after year three) and after getting the minutes, the change of style that suits him better, more shots, better shots, and tutelage from Malone and Sloan he hasn't substantially and obviously improved offensively, I'm comfortable calling that it's not going to happen.
But again, I'm rooting that he cans one simple post move, does well in the PnR, and can hit the high-post jumper with any kind of reliability. And passes better.
