It's not just the height; it's the overall length, which includes the arm length. When I compare to Griffin to Greene, Greene's length looks at least three inches taller. Granted, that's my "eyeball test", but after seeing thousands, of games over the years the "eyeball test" is probably pretty good.
Griffin has the arm length of Peja, which is not a compliment. He's not a very good post up player, and he's not a very good post defender.
Griffin is a "safe" pick. He will be a nice player to have on the roster. He'll be the "rebound guy." It's just that, in my opinion,
he doesn't have the capacity to be a star. At the end of the day, it wouldn't surprise me if four or five players in this draft end up better than Griffin. My guess is that Petrie isn't enthralled by him either. I have my doubts that he would pick him #1 if he had the #1 pick. The more I think about it, the more I think the Kings management might be better served to have a lower draft pick. Then they could more easily pick the player with the higher ceiling, but who is more raw basketball-wise. Maybe the #1 pick isn't so great after all....
