Five hundred nine is a pretty special number.

One hundred ten is even more impressive.

With three more touchdowns, Denver Broncos quarterback Peyton Manning will have thrown for more scores than anyone in NFL history. That mark will be revered, and deservedly so.

Those three touchdowns will also get Manning to 110 for his Broncos career, and that part of his time in the NFL is arguably even more impressive than his glory years with the Indianapolis Colts.

Only 117 quarterbacks have thrown 110 touchdown passes in their entire career, and Manning has done that in less than 2 1/2 seasons in Denver. Think Trent Dilfer had a decent career? He played from 1994-2007 with five teams, and won a Super Bowl. He had 113 touchdown passes in 14 seasons. Manning has nearly matched that starting at age 36.

Manning has more touchdowns for Denver than the following quarterbacks had in their NFL lifetimes: Chad Pennington, Jim McMahon, Doug Williams, Greg Landry, Jeff Hostetler and Elvis Grbac. The list goes on.

And to think there was serious doubt about whether Manning would ever throw a complete pass after four neck surgeries nearly wrecked his career. In 2011, he did not play a single down.

After his first throw in a Broncos' uniform, an incomplete pass in a preseason game in Chicago two years ago, Manning took a moment to absorb the meaning of throwing a football after 19 months without live competition. He was a medical marvel even then – well past his biological prime and coming off the kind of hiatus that could permanently derail even a healthy athlete. One sack could end his career, and two years later that threat still exists. He could have called it quits and walked into the Hall of Fame in 2016. Instead, he could very well walk into 2015 as the leader of the Super Bowl XLIX favorites (which the Broncos are according to online sports betting website Bovada) and the NFL's most popular team.

If Manning does win a Super Bowl for Denver, there's an argument to be made that his Broncos career would become even more sterling than his Colts tenure. His completion percentage has been better (68.2 to 64.9), his touchdown percentage has been better (7.5 to 5.5), and his interception percentage has been better (1.7 to 2.7).

Perhaps most impressively, his average yards-per-attempt is higher as a Bronco than it was as a Colt. He is the master of the short pass, but he's somehow more dangerous now, in his old age, after all those surgeries.
