Peyton Manning has given Denver Broncos fans much more than they could have asked for.

Manning was 36 when he signed with the Broncos in 2012, and he was coming off of neck surgery that forced him to miss an entire season. There were questions about his arm strength and his durability.

All he's done since is lead Denver to a 19-3 record while producing at an MVP rate. In six games this year he's already thrown 22 touchdowns to just two interceptions. His 2,179 passing yards lead the NFL. Most importantly, he's led the Broncos to a 6-0 record and put them in the driver's seat for a playoff bye.

And if you thought Manning's production on the field was impressive, wait until you hear about the quarterback's off-the-field impact.

TMZ called all 21 Denver-area Papa John's that Manning owns and inquired about business. Before Manning bought the restaurants, according to TMZ, they reported sales of around $3,000-$4,000 on game day. Now, that number has nearly doubled and is at about $5,000-$6,000 per day. That's 60 pizzas an hour.

Meanwhile, TMZ reports that neighboring Papa John's that are not owned by Manning did not report an increase in sales.

Sure, Manning may be taking some ribbing for his Papa John's investment. But from the looks of it, Manning will be laughing all the way to the bank.
