I tend to agree with the others here.
Sadly, defensive minded hustle guys (with average offensive game) is something have plenty off right now. Avery Bradley, Marcus Smart, Jae Crowder, Brandon Bass. I don't feel a guy like Green would add much to this team.
In fact, with so many of our guys being that type of player, I really feel we need an offensive oriented guy at the SF spot.
I do think Green would be an outstanding fit in a team like Sacramento or Detroit though - those teams could really use somebody with his mentality and skill set.
