To be fair, Carolina has a lot more than MJ. I suspect only UCLA could challenge for all-time NBA honors.
The question is what, if any, impact do Billy Cunningham, Robert McAdoo, Bobby Jones, Phil Ford, Walter Davis, James Worthy, Sam Perkins, Brad Daugherty, et. al. have on today's recruits. If Grant is ancient history, then what does that say about Charlie Scott, other than the fact that I'm getting old?
Right now, I think Duke has surpassed the Heels, at least on those rare nights when a good percentage of the guys are healthy enough to suit up. That may have more relevance to Duke.
But I would argue that anyone who says Duke can't produce quality NBA players either is too lazy to update an old and discredited world view or has an agenda. Or both.
