Are you seriously asking why we're trying to develop TT's offense? Do you not want our players to be effective two-way players our something?
Tristans only 22, he's not even close to peaking. He's already a good 1-on-1 defender, which is a lot more than most NBA players under 25 can say. Give him more time learning MB's system and he will be an elite defender at the 4.
Wasted pick, give me a break. Look at some of the picks around TT, would you rather have Derrick Williams or Bismak Biyombo? Faried made an early impact but his game has leveled off recently.
Klay would have been a nice pick, and the Cavs tried to move up to draft him. Kawhi wouldn't have developed nearly as fast here than in SA, it's debatable if he'd have been a better pick. It's been said before, if you redrafted that class now TT would still be in the top 5. Hardly a wasted pick.
Jack filled our backup point guard need, and he's great insurance if kyrie goes down. Considering we were giving Donald Sloan heavy minutes a couple years ago I'm not going to complain about Jack.
And finally, why are you in such a rush to trade Andy? Guy is our only legit option at center and on a favorable contract. He's too injury prone to have as much value to other teams as he does to the cavs.
