Koll actually retired from Cornell. I would imagine he is collecting his Cornell pension, in addition to his UNC salary.
Additionally, he is at a great academic school with one of the top brands in college sports. He won’t have to cut as many corners or deal with the same type of obstacles that he did at Cornell and Stanford. He is going yo do just fine. He probably won’t win nationals, but he can probably improve on what is already there and win a trophy if he stays around long enough.
