I think Green is the one Celtic that C's fans undervalue. He isn't a #1 scorer, and he struggled on a team with so few other good offensive options, but he is a solid starter with value on both ends of the court. I don't see #9 as a huge upgrade over #17 to be honest; to me it means getting Stauskas or Nurkic instead of Ennis or Capela, not a huge deal. Unless Smart or Gordon slips to 9 I'm pretty indifferent about this trade. However, I'd be a little surprised if Charlotte bites, as they will likely have someone they value highly at #9 (McDermott? Randle?)
