While I agree with you I would point out that Carr made plenty of money that wasn't in his contract either and as far as job security. Not many schools have better job security than Michigan. They have had what 3 coaches at Michigan in the last 40 years. I don't know of any other school with that much job security.
I will also agree that WV has had a good run lately and has a decent history but Michigan is the winningest program ever, has 11 national titles and has been to 33 straight bowl games, which is a record.
With all that said I don't think Rodriguiz is a good fit at Michigan. Personally I hate the offense he runs and don't want to see it at Michigan. While I think Michigan needs a more aggresive playcaller I don't think running a gimmicky offense is what they need.
Talking about job security, I think Joe Paterno has it........
