You’re probably right with Willingham, the coordinators, and the AD, but not the support staff and such.
The problem with those really highly paid folks is they highly spend to make up for the high paying salaries. Not a lot of bargain shopping or coupon clipping amongst head coaches and their families. When was the last time a WVU head football coach lived in 2500 sf house with a 2 car garage with a Silverado & a Camry in the garage? More like a 7000 sf house and a 6 car garage with an Olympic sized pool (and a Grato), tennis & full basketball courts, sitting on the lake with the party boat. For their sake they better have a good 6 month emergency fund on standby.
