Some here are suggesting that the Jazz will trade Kessler now that they've picked Flip, but I think they make a pretty good tandem at center for the Jazz. Kessler can defend the paint extremely well while Flip can defend out on the floor better and stretch the opponent's defense better. Both have weaknesses that need to be improved on, but the Jazz are pretty good at player development so that could happen.
The Jazz need an athletic wing that can step in and defend immediately and hopefully, develop into a reliable scorer too. They potentially got that in Williams.
Collier will be a strong PG to pair with Keyonte at SG.
I'd now like to see if the Jazz can trade Clarkson and other asset(s) for a solid (not necessarily star ... solid) starting SG. Probably just wishful thinking.
