I think this is a massive gamble for the Broncos. Its something that I think makes sense, but there have been too many people during the Manning sweepstakes who just assume that he will regain his form from a number of years ago. The two guys in recent memory who have had success into their late 30's were Elway and Favre, both of who I would consider better all around athletes than Manning. I am very interested to see how the Peyton experiment goes.
I think that this upcoming season and next season are his best shots. After that I think its a crap shoot as to whether or not he can play at a top tier level.
