Jeff is an excellent player. If you put him on the Heat or Spurs he's in their top 3 best players.
If the knock on him is that he's no superstar or he's not a guy who can create buckets on his own, fine. He's extremely capable in many facets of the game (defends wings like LeBron well, runs the break, drives well, hits 3's and mid-range jumpers, foul shots, team player, etc).
He's getting paid $8.7 M this year. That's a good value. He is not KD or LJ, but people act like he should be.
I'm bummed Jeff is only averaging 16.7 pts so far this year, but his FG% is good at .462, and his 3 pt % is great at .415.
Jeff Green could be the second best player on a championship team if he were paired with LeBron James and a bunch of other guys.
