Moore is also NTDP from that list. Personally, I wouldn't put stock in a Craig Button list to make a point. It looks pretty shoddily made.
But overall, the 2006's weren't a strong year for the NTDP. The 2007's are probably a little better, but probably not when it comes to extremely high picks. Hurts that Potter left a year early, but if we're counting players like Hagens and Hensler that are NTDP products that are going to be drafted out of college, he should count too.
Someone mentioned it, and I know every small center gets compared to him, but Brayden Point seems the closest comparison.
Not that those two comparisons are bad. I think Point is a little more accurate.
