You just know that the Phoenix Suns were involved in this fiasco. Please don't get on me if I screw this up! Trevor Ariza apparently was supposed to go to the Wizards - Kelly Oubre to the Grizzlies - and Austin Rivers, MarShon Brooks and Wayne Selden to the Suns.
Breaking: As part of a 3-team trade that has been agreed upon in principle, Trevor Ariza will go to the Wizards, Kelly Oubre to the Grizzlies and Austin Rivers, Wayne Selden and MarShon Brooks to the Suns, per @wojespn.
