Spurs should hold firm with Barnes, Vassell, 14 for Durant.
Just thinking about that trade package a bit more for Phoenix.
G: Tyus Jones, Grayson Allen
G: B Beal, D Vassell
F: D Booker, Cody Martin, R Dunn
F: H Barnes, R O'Neale
C: N Richards, (free agent)
Why bother?
(1) A downgrade from Durant to H Barnes. Expiring contract. Leaves in the summer. Not a good PF either. H Barnes is too much of a finesse player. He is a shooting SF who plays on the perimeter. He lacks the physicality to rebound and defend the PF position.
(2) Devin Vassell plays the same position as both Devin Booker and Bradley Beal. None of the three play a 2nd position effectively. They are all one-position players. They are all scorers and lack the mentality to play PG. They are too small and deficient in terms of defense & rebounding to play SF effectively. Phoenix are committed to Devin Booker long term. There is no role here for Vassell. At best a 15mpg backup. Or give him longer minutes and play unbalanced ineffective lineups.
(3) The #14 pick. One mid-first rounder. That's it.
That is terrible value for Durant. Even at 37 years of age he has more value than that. He is a massive difference maker for a playoff team. Phoenix need to be getting back multiples picks or superior veterans back in return.
