And as for your over-estimation of Ohio State's impact on Tom Herman, well ... Herman's 22-year coaching career started in 1998 at ...
1998: Texas Lutheran (Texas)
1999 - 2000: University of Texas (Texas)
2001 - 2004: Sam Houston State (Texas)
2005 - 2006: Texas State (Texas)
2007 - 2008: Rice (Texas)
2009 - 2011: Iowa State (Iowa)
2012 - 2014: Ohio State (Ohio)
2015 - 2016: University of Houston (Texas)
2017 - 2020: University of Texas (Texas).
So, as you can see, 73% of his coaching career has been developed in the art of Texas football, rather than the nuances of Ohio tiddlywinks.
