I think he'll play until he decides that he can no longer play the game at the level he currently can. I think he was a little off last night in the 1st half, but he put on a show in the 2nd half. I think even if we win the Super Bowl this year, he'll likely be back next year, from the looks of last night. Once his playing career is done, I suspect he'll become an elite coach in short order.
As a football fan, I'm just enjoying watching him while I can. Even before he became a Bronco, I was a huge P. Manning fan, in spite of all of the dreadful defeats we endured against his Colts. He is simple a very special player that doesn't come around often. As a Bronco fan, I'm ecstatic that we once again have a great QB at the helm after a long dry spell.
