Okay, I know I shouldn't compare apples and oranges, but;
Buddy Franklin, freakishly talent, massive upside, gigantic, quick, great leap yadda yadda pre-draft hype but was a complete tosspot with a poor attitude.
From what I've seen in a few interviews, Naitanui has a fantastic, positive, refreshing attitude, he works hard (and his transition to the game required hard work) I don't see a reason why he wouldn't make it, yet how on earth would H know? He might get injured in his first game.
