I'd trade Kanter, Burke and a bunch of picks to the T'wolves for Andrew Wiggins, but that's the only deal I'd be looking to make right now. Anything short of that trade and I think they should just roll with the guys they already have. Wiggins would address their wing scoring and defensive issues, and give the Jazz two potential #1 prospects to develop together.
I'd love to see a lineup of Gobert, Favors, Wiggins, Hayward and Exum with Burks as the 6th man off the bench. Hayward can play some 3, Favors can play some 5 and you look to draft and sign depth to compliment your young starting lineup. I'm assuming that this deal would also require the Jazz to take on K-Mart (who I'd keep to mentor the young guards) and Berea (who I'd ship out with some 2nd round picks.)
If the Jazz can't get that deal, they should stick with Burke and Kanter and see how they look in Snyder's new system. Maybe look at trade options at the deadline. I wouldn't make a move this year for anything less than Wiggins though.
