Retiring following the 1997 season at the age of 72, Marv Levy joined George Halas as the oldest coaches to man the sidelines in an NFL game.

Nearly two decades after he retired, would the Hall of Fame coach return to the sidelines? Would he return to the Bills?

Yes.

During an appearance on the Levack and Goz show on Albany's104.5 The Team ESPN Radio, at 91, Levy said he'd "consider" returning to Buffalo if the Bills offered him the job.

"If they offered I might do it," he said. "After 47-years of coaching I really needed to get that deep breathe to step aside. But after a few years I would have liked to have gone back.

"I'd do it, but I'm not deluding myself to think an offer would come. If it did, I sure would consider it. Sure."

Levy also explained that it's not about age, but "readiness and ability" to perform the job responsibility of a head coach.

Tom Coughlin, who is 70, is considered one of the top candidates to replace Rex Ryan in Buffalo. After retiring from the Giants in 2016, Coughlin served as a "senior advisor" in the NFL this past season.

He reportedly interviewed for the Jaguars head coaching job on Wednesday. Coughlin coached the Jags from 1995-2002.

"You evaluate will the man still have the energy he needs? I certainly felt I did," Levy said. "Maybe Tom does too."
