Earlier this season there was a theory that Jim Tressel was sitting up in the booth waiting for an opening on the sideline. That said, Mike Chappell thinks the possibility of Tressel taking over for Caldwell is pretty unlikely:
ANSWER: Every coach’s job is uncertain, starting with Jim Caldwell and including Tressel. Not much that goes on in the NFL shocks me anymore, but I would be absolutely floored if the Colts got rid of Caldwell and replaced him with Tressel. Absolutely floored. If Caldwell is retained, there’s a chance Tressel returns in the same role as before (replay consultant). If general manager Ryan Grigson decides to bring in his own people, all bets are off.
