what kind of coach you looking for?
program?, gameday?, player development?, turning out young MEN to be set loose on the world?
Saban, Spurrier, (a 'more with less coach, maybe Malzahn? Alverez?), and Richt answers those divisions imHo..
Saban delegates. he's a program manager not different than an engaged CEO. Meyer and Spurrier are hands on. Alverez or Gus, Petterson or Peterson are 'more with less' and build impacting teams regularly, and Richt is a dying breed (though he's obviously exited) that I appreciate most- he teaches those kids more than just the game and prepares them for life during and after... there are few of these anymore, and that's a shame. the game is now 'money' and anything/everything else follows.
Larry Kehres. There is your GOAT. he did it ALL.
