Spurs have Fox, Vasell and will land Dylan Harper, so they take advantage of their situation and sell high on Castle.
Wiggins is a great fit as a 3&D wing.
SA can play a very well balanced starting lineup of Fox, Vassell, Wiggins, Barnes, Wemby. With Harper from the bench until he is ready to start
Miami lands Herro’s running mate for the future, a guard who can cover him defensively, and finally a high draft pick who they can develop, they have done a great Kobe with lower picks already, there is no reason to believe Castle can’t become elite with the Heat developmental program.
