Here is an interesting, yet admittedly-limited look at college football coaching from Bill Connelly: measuring results relative to win expectancy. (You just fell asleep when I mentioned advanced statistics, didn’t you. YOU WOULD.) It’s only one small piece of the picture in terms of measuring coaching acumen in football, which is super difficult and probably impossible, but it sheds some light on who is overachieving or getting fired.
In six seasons as a head coach, Dave Doeren has had basically zero impact, year-to-year, on his teams’ bottom line. Statistically his teams have underachieved by -0.03 wins per season, which ranks the Deezy 104th out of 224 coaches in this sample.
