I'd honestly go with the Nets group for the coming future. I like Devin Harris, Courtney Lee, Chris Douglas Roberts/Terrence Williams, Yi Jianlian and Brook Lopez more than I like Randy Foye, Mike Miller, Josh Howard, Andray Blatche and Javale McGee, on a purely talent stand point. They are also much younger and the Nets should most likely have a better draft pick than the Wizards which will also help in the near future.
But I see the Wizards having a better record in the remainder of the season, but I'd rather work with the Nets talent than the Wizards at this juncture.
