Mark Dantonio was HC at MSU for 13 years, just like John Cooper was at OSU for 13 years. Actually similar records, Dantonio had won more win, but more losses, as his teams actually played considerably more games over the span of the 13 years.
So, if you had to have one of them as HC at OSU for 13 years I am assuming everyone picks Dantonio based on the record against TTUN?
