I think he stays. The last few drafts don't seem to be as bad as they have been the last 20 years. He is making the team younger and rebuilding. The defense was solid last year until they wore down, because of the 3 and outs that the offense had most series.
Best case scenario and least likely, I am right and he does well.
Worst case he bombs the next two years and he gets to go and we finally rid ourselves of King Carl
