Far-fetched rumors in Lakerland have them landing Durrant this summer and Westbrook the following year. That would certainly tick off the rest of the league.
But the Jazz are in a good place if they can stay healthy, see more improvement from Favors, Hood, and Exum. I think Hayward has just about peaked but he should have 3 or 4 really strong peak years.
Also, this team is made to be the kryptonite for the warriors. I don't think that's possible with the Warriors playing at this year's level, but if they regress and the Jazz keep improving, the Jazz will cause them fits.
