My point exactly! He has been on the short list of every NFL HC shortlist for the past 5 years. He has proven himself as an offensive play caller and yet hasn't been given the opportunity to become a HC. This path provides an opportunity for NFL teams to either shit or get off the pot. If they get off the pot and pass on him as their HC then it provides a clear path in a very short period of time to become a college head coach.
My proposition would be simple. He will be paid current salary plus some. He will be named the HC in waiting and given full reins of the Iowa offense. Ferentz can suck on lemons for all I care.
Reasoning:
Ferentz buyout is too hefty of a price just to get rid of him but you can certainly take some of the control away from him by making a hire of this caliber. Should Ferentz not enjoy the powerplay then he can retire, which he won't do until he has the .600 winning percentage required to be eligible for the Hall of Fame.
If I'm Bieniemy I see it for exactly what it is. A clear path to a HC position either at the college ranks at a power 5 conference or in the NFL.
