Why the Wizards do it - Anticipating a healthy John Wall coming back, the Wizards go in for a potential superstar center in James Wiseman, take on Wiggins to be their third man behind Wall and Beal and keep Hachimura.
Why the Warriors do it - They get to drop Wiggins and pickup three very young, cheap players in his stead. Dropping down 7 spots in a draft that has no sure thing is a small price to pay for a good caliber starting center and two young wings who can grow with this system.
