What else does he do besides score? Rebound? No. Assists? No. The guy plays most games like he is not interested.
Defense is half of the game and he plays it really well. And with versatility.
If anyone watched Jeff Green play defense I don't see how they can say "oh he isn't interested". Does no one watch defense?
I'm not saying he is one of your core players to build around. But he isn't overpaid like people say for what he brings and he's a really nice complementary player. An effecient player who scores 16 a night on average, spaces the floor, shoots threes well, is a good defender, has length, and every once in a while really goes off.
Nothing to be so negative about.
