When Duncan came out, was he known as a good defender? Or did people question it like they doing with Jah?
No, Tim was a star, day one. He was the last of a dying breed, that played 4 years in college, dominated, and covered every base. Fundamental, Offense, Defense, intangibles, he was the real deal, day 1.
Okafor could very well be that, if he stayed in college for 3 more years. But the game has changed, people don't do that anymore, hence the "uncertainty" now with draft picks.
