How about Jeff Saturday? I can't imagine him wanting to come back and play if the Colts part ways with Manning and select Andrew Luck (as I'm starting to see as a virtual lock). Does he really want to endure a 2-14 team rebuilding with a rookie QB? I imagine he could teach the team's OL philosophies as well as anyone, since he's been helping newcomers catch on for the last several years. And he definitely has the intelligence, passion, and drive. Just a thought...
