It's a formality, but for the Broncos, it's bigger than any move theyr'e about to make. Peyton Manning passed his physical, which (for now) guarantees his 2013 and 2014 salaries at $20M per year.
But like the recent Tom Brady and Joe Flacco deals, this is not a full guarantee. Should Manning suffer a reaggravation of his neck injury in 2013, his 2014 salary will no longer be guaranteed.
