If the Ayton-Suns relationship becomes untenable.
I can’t imagine the trade market for Ayton will be crazy given the lack of interest in him over the summer, and the lack of leverage the suns would have if desperate.
This gives the Suns a replacement on a shorter contract. Porzingis quietly had a really nice season last year, and would pair well with Book and CP. It also gives the suns high quality depth in exchange for expiring contracts.
This gives the Wizards a young piece that should pair well with Beal. It also frees up some cap space next offseason, giving them additional flexibility to maneuver.
