There might never be another JC nationally. Build his own program from scratch into a 3 time NC program. And then have it continue for a bit after. That's other worldly. Guys like K can't even claim that.
That's the important point here: he doesn't have to be a Calhoun. He has to come in and take a program with history and a fertile recruiting ground somewhere near where it was. Lest we forget, JC missed the NCAAs 1 out of every 4 years. In the AAC you should be able to make it pretty much every year.
The highs are still competing for a NC, though maybe less regularly, but the lows not be as low.
After the last 3.5 years, the next coach doesn't have to do a ton to win us over. Some programs never recover (Indiana isn't
really back yet), and some hit a bump and then bounce back. We're not UNC, and never will be. But we have more NCs, and a more recent history of multiple NCs, than UNC did when Roy came.
In other words, the world has changed and we aren't going to get someone as good as JC. But we don't need one to be in the national picture.
