Former Broncos great quarterback John Elway walked away from football at age 38 as a Super Bowl champion for the second time in his career. Elway retired after Super Bowl XXXIII, rode off into the fairy-tale sunset on top — en route to enormous entrepreneurial off-the-field success.

Current Broncos great quarterback Peyton Manning is 37, and he is one AFC Championship Game win over the Patriots Sunday away from having the chance to win the second Super Bowl title of his brilliant career.

Is it possible Manning pulls an Elway and walks away if he and the Broncos win Super Bowl XLVIII at MetLife Stadium?

Elway, pondering that question during a sit-down round-table interview Thursday at the Broncos training facility, said: “You know, I don’t know. I still think he’s young and he’s playing well. That’s going to come down to Peyton. It’s going to come down to what he wants to do.

“We’ll sit down after the season and find out where he is and what his thinking is. But to be where we are right now and talk to him about the future, I don’t think is productive right now.”

Manning has dropped hints in recent interviews his career is nearing its end in the context of the importance of taking advantage of this playoff opportunity because he doesn’t know when — or if — he’ll have another chance at winning a Super Bowl.
