I can't think of a worse thing to do than take a team that has been through what this one has and send them a coach with a resounding Mighty Mouse cheer "Here I am to save the day!" Plus, tell Fickell "sorry, Bub, moving back to defense, there's a new sheriff in town."
What would be gained with this one month for one meaningless game between two mediocre teams is far outweighed by taking the opportunity for the new coach to start on staff and player recruiting. Let the lame ducks have one last hurrah.
