The thing about the UM job is that its a pure filter for the invisible hand. Once you take the UM job the marketplace knows exactly what you're truly worth. Guys like Schnelly, JJ, Errickson, and Butch all ended up with multiple high level job offers throughout their careers. Guys like Randy and Golden were never and will never be offered head coaching jobs again. Coker proved to be a sound coach who was best suited for a lower level college program. The market place got him to UT San Antonio before he retired.
I'll go ahead and put Manny in the al golden category. He will never be offered a head coaching job again and likely will never be offered a coordinator job again either. Im not sure Manny will be employable as a coach going forward. The marketplace does not think of him as a coach. My guess is that he goes into sports marketing or something similar after UM Management does what must be done.
