Viewing as a long-term investment I'd have to give it a B+, we still have years of all-star play by Kyrie. He'll be in his prime when Brown, Tatum, Rozier, and even Semi are moving into their prime.
Unfortunately, that Nets pick could produce a future star, other than that we unloaded a potentially overpaid, undersized, one trick pony, and middle of the road small forward.
With normal luck...the future is bright.
