I think we should go after Gerald for next season AND sign antoine. 
He's already been replaced with walker, giddens or pruitt take your pick, add in next years draft pick
Gerald isn't smart enough to play in the nba. He can dunk and has a nice shot. A perfect point of why guys should go to college. Or play in the d league until they learn proper. With europes pick and roll plays and solid d I'm not sure how he'll do in europe.
globetrotters?
Yeps. I don't think there's a good contract in Europe waiting for Gerald. There are literally hundreds of players better than Green - especially from the perspective of FIBA basketball - fighting for contracts in Europe. Unless he's willing to play in countries like Portugal, Finland, UK, etc, but in that case the contract is not going to be that good. In fact, I wouldn't recommend his acquisition by our ball club and our best player is a former NCAA Div 2 Player of the Year who never had a realistic chance of playing in the NBA (the closest he went was a pre-draft workout for the 76ers).
I think Green should try China or another Asian League to make some money. He's not good enough to play pro-basketball at a high level.
