I like Harbs a lot-I don't get the feeling he's leaving Michigan, and he turned us down last time. He's the best retread of the bunch that's been mentioned.
Plz no to Dan Quinn or Bill O'Brien as two guys I could see getting let go and names bandied about. freak no to either.
Kubiak is a likely non-candidate due to his health issues and the way in which a very close friend of his (Dennison) had beef with the organization for his one year here. If Gary Kubiak wants to be a head coach again, he'll have numerous opportunities.
Dennis Allen had absolutely zero shot to succeed in his first NFL job and has done well in New Orleans since, but with any defensive coach its going to be bigly o-coordinator dependent.
