Terrible trade for the Wizards. Why would a rebuilding franchise give up two 1st round picks (even protected ones) and three 2nd round picks for a guy who is always injured and will likely retire in the next few years. Let's face it - AD is aging badly. None of the other players on either side of the trade are worth much. Middleton is at the end of his career as well, and D Russell has always been a bit of an enigma. It's basically a trade for an aging oft-injured player in return for a slew of draft picks.
Of course, this is a lousy trade for Dallas as well. Since AD barely had a cup of coffee with them (based on games played), you basically gave up Luka for two low 1st round picks and a bunch of 2nds...that is why their GM is now unemployed.
