The ACC is very top heavy, which is why so many think it is the best conference (and that Coach K tells them that), but from top to bottom not so much.

What happens if Duke and Syracuse struggle for a few years post Coaches K and Boeheim (like UNC and others)?
These two have been their basketball program for so long, few recall what they were like before these coaches were there. Boeheim head coach at Syracuse since 1976 and K head at Duke since 1980.

They are going to play the tourney in NY in 2017. Coach K will be 70 and Boeheim will be 72. After these two are done, will anyone else in the league (other than ESPN) really care if the tourney is in NY?
