Broncos did have like 3 or 4 possessions in OT. Their legendary QB threw an awful INT. It happens.
Not sure what I would have done. Like Fox said, the team was in a state of shock. He knows his team better than anybody. If they won the game we would never even mention it. That is the way these things go.
BTW, I think if Peyton insisted on not kneeling they wouldn't have kneeled.
