For free agents that don't have contracts for next year, it's a great move. For Williams, it's also a great move. Even if he gets hurt, the Nets have to resign him--they gave up so much to get him.
I think if you get a few more all-star caliber players moving overseas, this lockout will quickly end.
As for Zaza, I'd like to see him dominate overseas and build-up some confidence.
