Ugh, no. Even though Sexton isnt as bad as advertized by some. However, I dont think he moves the needle. The other two, meh. And Cavs wont do it either.
Regarding the Bulls - I would like Thad Young, Shaquille, Dunn and Hutchinson.
We could sign Shaquille Harrison right away. Prpblem with him, is that he has limited height. Good defender though. And iirc he's a free agent, and peobably one of the under the radar ones. Dunn is the other one and even though I love his defense, he can't shoot. He can play with both CJ and Dame, though and he can handle the ball a bit, unlike Shaquille. Shaq has a QO of 1.7M (might/should get) and Dunn of 7M (doubt it).
The problem with acquiring Thad, is that we'd need to give up either CJ or Ariza. Moving Thad for Ariza doesn't make much sense if we'd keep Melo around imo. If we'd be interested in Hutchinson, we'd probably need to give up Zach Collins (and Kornet would come back our way alongside Hutchinson - both good fits), IF the Bulls are willing to give Zach a look.
Please correct me if I'm wrong here on contracts.
Harkless is obviously a UFA, but that wouldnt move the needle at all. There aren't many UFA options this summer at SF which would help us more than having Ariza back: Demarre Carroll, Crowder, Solomon Hill, MKG, RHJ, Wilson Chandler, Thabo, Stanley Johnson, Josh Jackson, Evan Turner. Meh. And the one who would be a good fit, Gallo, is way out of our range, and I'm assuming DJjr is going to stay in Miami (he'd be a good get).
At PF, Milsapp, as someone mentioned, would be terrific, at the right price. So would one of the Morrii brothers. Dont want any part of Patrick Patterson or Vonleh. Marvin Williams is UFA, he'd be perfect (I think we'll end up with him). And, even though he doesnt shoot the three, Harry Giles would be interesting, with his upside and passing. Too expensive, I guess, much like Wood, though. Juancho is UFA as well, but I doubt he ever really amounts to something. He has shown flashes.
