Wouldn't be surprised if Jerry has already verbally promised him the job if he keeps progressing. (They had a discussion when Kellen was offered the Boise State job). I don't think that means he will fire MM if the team has a winning record and makes a good run. I think it's similar to the Josh McDaniels situation in New England, another head coach in waiting. Basically be patient, keep doing well and the job will be yours further down the line if you stick around.
