I agree...K didn't take the amount of elite kids he has over the past 3 years, plus he coached many years when kids were going straight from HS. Kobe Bryant would have gone to Duke, hands down...and you'd have other cases of that. K was able to win a LOT by having either a bunch of veteran players, or very solid role players around 1 or 2 elite guys...now he's winning with the Cal method of load up on OAD players. So he's pretty much proven he can win with various tactics.
Irving, Parker, Okafor are all-stars...period. Will be interesting to see how Winslow and Jones translate, but my guess is they have very solid careers.
