I don't see the infatuation with H. Barnes around here. He is a decent player, but is probably expected to be about as good as Jeff Green. Throwing in a first is apparently about his potential (?). He is younger and would probably be a better fit with our team, but Green would probably fit in better with them.
The love / hate for Green is funny around here. He is either going to be a 25 ppg scorer or apparently couldn't fetch us a late first round pick from a contending team. Green is a nice piece for ANY team. He is efficient, versatile, and productive. Just because he isn't the next Durant doesn't make him the next Giddens either.
I would probably consider the trade straight up (without the first) because it makes us a little younger and a little worse, but neither side has that much to gain by switching small forwards right now.
