Update:
Since the deal below (Ariza to Wizards, Rivers to Suns, Oubre to Grizzlies) was announced, the principal news breakers—Adrian Wojnarowski of ESPN and John Gambadoro of Arizona Sports 98.7—have been in a Twitter tug-of-war over role-players included to make the trade fly. Gambadoro has insisted the Suns are receiving swingman Dillon Brooks (6’6, 22-year old). Wojnarowski has countered, saying the Grizzlies are sending MarShon Brooks (6’5, 30-year-old shooting guard).
As it turns out, they may both be right...and wrong. Apparently the Grizzlies and Suns themselves are confused which Brooks is to be included, and the difference may scuttle the deal.
