I think we should be past the point where Green is knocked for his size. Like its directly due to his ability to defend the post at a high level that your teams small ball lineup is so dominant. They remain great defensively b/c he compensates for a lack of height so well, and has a team that can help him on tough assignments if need be.
I'm not knocking him for his size. I just don't think he's capable of even slowing down the most prolific scorer in history. If Kareem was going against Wilt, Parrish, and Russell I don't believe under any circumstances he's going to have problems with Draymond Green. Just because he's effective against Dwight Howard (he's an offensive midget) or D'andre (again offensive midget) or Ibaka (jump shooting big) in the post doesn't mean he's going to give Cap any trouble especially when Boogie would give Draymond fits
