I guess the question to ask here is: Are the Wizards better off over the next few years with Nene than they would be otherwise?

There are two things to keep in mind here:

Nene's acquisition caused the Wizards to take on more immediate salary so they could offload Nick Young and JaVale McGee.
By offloading McGee, the Wizards weren't the ones who had to figure out how much money to give such an athletically-gifted and frustrating big man.

The message sent by the trade for Nene from Washington's perspective was simple: If you're not serious about basketball 100 percent of the time, we don't want you. Whether it was too harsh or poorly-executed, it hardly matters. What's done is done, and the intent has materialized into results.

Getting rid of McGee saved the headache of trying to figure out what to pay him; that was Denver's job, and it looks like the Nuggets and McGee are getting along well. No McGee also meant no personality overshadowing contribution. By all accounts, McGee is a good guy, but the fit wasn't right.
