The Suns and Kevin Durant are expected to work on a trade out of Phoenix this summer.
KD had interest in Knicks, Timberwolves, Rockets, Spurs, and Heat at this past trade deadline, per Shams Charania
Send Mikal Bridges back to Phoenix with KD replacing him in NY 
(I do think his best, more realistic options are the Spurs or Rockets)
That would be cool. Probably M Robinson and M Bridges for K Durant.
KnicksG: Brunson, McBride
G: J Hart
F: Anunoby
F: Durant
C: Towns, Achiuwa
That Knicks team would be immense. So much firepower. Great role player wings around their 3 offensive players.
SunsG: Beal
G: D Booker, G Allen
F: M Bridges, R Dunn
F: R O'Neale, Cody Martin
C: M Robinson, N Richards
I wonder if there is any type of deal out there that would allow Phoenix to offload Beal in a Durant deal. Keeping him maintains that problem in the backcourt. Another problem at big forward with Durant leaving. He is their only true big forward on the roster. M Robinson would be a good upgrade at center for them over their current options.
Still, that team with their current chemistry issues which would likely continue due to the mismatch of Beal & Booker would likely struggle to be a .500 team. Maybe a 35 win squad.
Talent wise they should be good enough to be a 40-45 win team ... but I expect they will continue to underachieve as they have done this year due to tough roster balance.
