Makes sense for Green and Memphis. He is signed for for a reasonable amount - Memphis will be able to make a more informed decision on if he is a part of their future and Green should be able to cash in on a slightly bigger deal.
For all of Green's haters, he has been productive throughout his career. I say it all the time, but he is pretty locked in as the 6th best player from his respective draft (depending on how you feel about Thad Young). Just because he never 'wowed' like he was supposed doesn't mean he was a disappointment. For his (and Memphis') sake, I hope he continues to produce. As a bonus, he has always been a good guy, too.
