Tough call. Do we eliminate Head Coaches who clearly act as titular OC’s like Ryan Day, Kiffin, Sarkisian, Riley, Dillingham etc?
I don’t pretend to know the value of every current OC in FBS but Kendal Briles and Jeff Lebby are definitely ahead of Ludwig. Ryan Grubb at UW, the guy Saban hired away from Notre Dame (Rees?), Monken (is he back in the NFL?), is Chad Morris an OC again? Spavital, Seth Littrel, Kingsbury is back at SC.,,
A really good OC usually gets a head coaching gig at some point in his career and I don’t know that Ludwig has ever been in the running. I also don’t know if he has ever interviewed so it could be by choice.
