I thought Jeff Green struggled in terms of defense and rebounding for the majority of his time here. He didn't give a true account of himself in either area. Capable of more.
Offense was about right. I don't view him as a scorer at SF. At PF, yes. Not as SF. Complementary piece.
That's exactly how I see it. I think at times they struggled to understand how to best use him offensively (or he struggled to understand it), but he pretty much is who he is on that side.
Defensively though, I think he struggled with the system early, as well as the switching back and forth between positions, which held him back. He is never going to be a great defender, but I think with some games under his belt, and more time spent playing as a true SF, he can be a very solid one.
As far as the numbers go...it sounds like people are trying to talk themselves out of what their eyes told them with numbers, and that is usually not a good idea.
Green most certainly struggled. He wasn't as bad as some say (I think a lot of people expected WAY too much from him, based on who he was traded for), but he most certainly wasn't very good either.
He was, however, good enough to get another chance...if the contract allows. Let him show what he can do with some time in the system to adapt (and with the rest of the team engaged), and I think he could become a very good player. But of course, it all comes down to the price.
