He has an opt out clause once the lock-out ends, so this contract will not interfere with any NBA activities, whenever they are resumed.
I personally think this is a good sign that he is the first big name to sign abroad during the lock-out. This means he is very serious about getting his wrist and game back to the level it was at when he was the best PG in the NBA.
We all know we must upgrade our roster in order to keep him, but his play (when healthy) is going to make our current assets much better as well.
If he is playing full speed after an offseason and training camp (I still believe this lock out wont cause the NBA to miss much) our overall team play is going to get much better.
So overall I think this is a great move for him and think it will help the Nets take a step forward this season.
