He is still a kid, youngest player in the draft i think?
That being said, he just never had that aggression in college.. and despite his measurables and athleticism, he could never take over a game in college. Marcus was doing that from day 1 two years ago. Ed Davis was a physical speciman back then too, but he's still soft as puddy tat now.
It's one thing to have crazy measureables (which both marcus and noah have), but it's another thing to make full use of it.
