Never happen.Fire barta first
The problem is....the powers-that-be at the University of Iowa do not care about athletics. Until that mindset changes (and I don't see that happening for quite awhile...if ever), athletics will just be something that is tolerated as a necessary evil, and for the money it brings in (which will happen whether Iowa football/basketball teams are good or bad).
Barta leaves....the U. will just hire another "fundraiser" to replace him.
