This is 100% a long-shot attempt at getting Durant. KD likes Brooks, and obviously he's from the DC area, so the Wizards are still hopeful. Also, this could be a 2017 move as well. If KD signs a one-year deal, and Brooks can get Washington to improve to a top 4 East team, maybe KD will give Washington a real look in 2017.
After the Gilbert Arenas-Javaris Crittenden incident, the Wizards have become a very risk-averse franchise. Brooks is exactly the kind of safe hire I'd have expected. That he has ties to KD is gravy. I think they should have played it less safe and made a run at Kevin Ollie, myself.
