This is a very fair analysis IMO. Personally, I'd move the Tristan walking to the pros list -- we were never going to get real value for him and we avoided overpaying him. If we're evaluating Altman just from the rebuild, the Irving trade would also be removed entirely from the list.It's all part of it
PROS CONS Allen Trade/extension Andre Drummond trade/buy-out Sexton draft Porter miss-handling Garland Draft Windler draft instead of Keldon Johnson Okoro Draft Kevin Love extension Mobely Draft (so far) John Beilein hire Rubio Trade (on paper anyway) Triston Thompson walking (function of Drummond trade) '17-18 mid-season re-tool around LeBron lack of vets to force internal competition Wade/Stevens diamond in the rough finds Irving trade Larry Nance extension Brodric Thomas with a roster spot
The big blunders were the Love extension and the Beilein hire. The others are relatively minor negatives, and every team has plenty of those.
IMO, Altman has done a good job at accumulating talent––between the lottery picks and Allen trade––which is the most important part of a rebuild. The next step is forming a coherent team, and the jury is still out on whether or not Altman has that in him. We may still be another year of talent accumulation away from reaching that stage.
