Peyton Manning Measures Up In Broncos Debut

There was an unfamiliar air of uncertainty surrounding Peyton Manning's debut as a Denver Bronco on Sunday night. From 1999 through 2010, Manning defined the quarterback position, throwing for over 50,000 yards with an adjusted net yards per passing attempt (per Pro-Football-Reference) of 7.24. Only Philip Rivers's 7.26 mark bests Manning, and Rivers did it in 112 fewer starts and with a higher percentage of his play coming in the recent League of the Quarterback.

For the first time since Manning opened 2010 with the Colts, we really just didn't know what to expect. Sure, "he's Peyton Manning," but multiple neck surgeries have the potential to derail any sports career, uch less one as fragile as NFL quarterback. There was talk he had become a reverse Zoolander -- instead of losing his ability to turn left, rumors mounted that Manning had lost the ability to throw to his right.

In that case, Sunday night's performance against the Steelers was Manning's Magnum.
