After winning 6th man of the year and a likely championship, big body starts gaining just as big of a head and as such wants to be the "alpha dog elsewhere" so he requests a trade. Given his roots in the DMV, he tells the media that he only wants to get traded to the wizards and turns the whole process into a circus by acting out in the most big body way possible. The spurs, needing big man/wing depth, decided to reluctantly make a deal where they get all that plus a first while the wizards add their linchpin on the burgeoning superteam.
