The thing is too, that he already is very disciplined and you can tell he works hard on his game. If he can learn from a guy like datsyuk or z at 19 he will be that much better, that much faster. Yes probably the perfect candidate for them to groom
This is the biggest reason I'm cool with him coming up this early. He likely is more ready than not ready, and the more time he gets with Dats and Z, the better.
