It's interesting that individually the assistants appear underpaid but together they're in the top 10 as a staff.
Meaning there are schools who have one or two highly paid assistants but other guys not getting their fair share. This is probably the issue at Wiscy and other Big 10 schools. There are 3 SEC schools in the top 8 in staff salary. And we wonder why the young energetic minds/recruiters get plucked.
It's not about the def or off coordinators, its those position coaches who also seal the deal on the recruiting trail or have good regional connections. Until Big 10 schools (outside of tOSU) treat their whole staff right, the collective mediocrity will continue.
