Five unexpected developments through 16 weeks of this NFL season:
That it would be Peyton and not Eli to be the Manning whose team clinched a playoff berth before Christmas.
That Adrian Peterson would turn a comeback season into a season for the ages.
That Robert Griffin III and Andrew Luck would make that big of a difference for their teams as rookies.
That division foes such as the Seahawks and Rams would become jarring speed bumps for the 49ers.
That the Jets seemed so determined to fail with Mark Sanchez rather than seeing if Tim Tebow could re-create some of the magic he performed last season.
