I think Jeff Green is fully capable of being a 15 point, 6 rebound a game starter on a championship team - especially if he continues to improve defensively at the SF spot.
He isn't a 1st or 2nd option, more like a 3rd or 4th option on said hypothetical team. And that's fine, you need 3rd and 4th options on all teams.
Also, as our team is currently constructed he will continue to struggle. The more open ended, fast break environment he is in the better.
I'd lie to see a lot more of:
KG
Sully
Green
Bradley and Rondo
Isn't that one of our top 2-3 lineups? I thought I read that somewhere.
I'm giving Green a full year coming off major surgery before I place too much judgement on him.
He's averaging almost 10 points a game in only 23 minutes. I don't 15 a game is a stretch with another 10-12 minutes a night.
Lastly, guys make leaps at different stages in their careers and in different areas of their game. With his athleticism he could very well become an outstanding defender at the three spot - combine that with 12-15 a night and 6 boards that would be very valuable, especially if you have a couple of young big guns putting up big numbers beside that contribution from Green.
It all depends what expectations you place on Green.
