Ok so I've never met Green face-to-face, but I have talked to the Giles brothers and Peavy, and they've said that Green isn't as "blah" as he might seem. He does have a personality, but obviously doesn't show it very often. They've said that it's just because he doesn't want his emotions to get the best of him during the game and cause him to do something stupid. But in the clubhouse he's apparently a great guy to be around.
