I think Smith has hit his potential were Green May have not even come close to it. You think about it, he hasn't been the first or second option on the team and still had average around 14 points a game, and that was with playing behind one of the best scorers int he league.
And with Greens medical scare, that might make him hungry, not take the game for granted. I'll be excited to see how he plays after the all star break next season. Its going to take him a while to get back into the flow being out for over a year.
The thing that I really like about Green is his personality. He's not going to cause trouble, he's the yang to Rondos ying. And the fact that the guy has been hanging around the team when he doesn't have to show character, and some one that actually wants to be here.
