If he has the kind of fire in his belly that Ziggy did then he will come home, get stronger, start learning the game and work everyday to develop. So many players have all the physical tools, but lack the mental toughness will shut things down. Let's face it...the NFL is filled with guys who's work ethic overcame a lack of pure natural tools.
I'd look to see this kid become an all-world DT and I believe that Kalani and Coach Tuiaki are as well prepared to develop him as anyone there is. Could be a great confluence of people in the right place at the right time.
