Peyton Manning's 33 touchdown passes this season are more than Chiefs quarterbacks have combined for in the last three seasons (30).

Percy Harvin will become just the second Pro Bowl player to make his debut against his former team after being traded since 1994 (as far back as we can check). You might remember the other player to do so: Darrelle Revis, whose Buccaneers played (and lost) to the Jets in Week 1.

Drew Brees has 18 TD passes at home this season, more than the total of 24 other teams, home and away.

Nick Foles has thrown 16 touchdown passes this season and zero interceptions, which puts him just four TD passes behind Peyton Manning's NFL record to start a season. But Peyton has more than just Foles to worry about right now; two other NFL quarterbacks have started their climb toward the four-time league MVP. Jason Campbell has thrown 5 TD passes without an INT to start his season, and Case Keenum has thrown 7 TD passes without an INT to start his 2013 campaign.

The Patriots have dropped the highest percentage of catchable balls in the NFL at 12.2 percent. Their total of 27 dropped passes this season is second-most in the league). Aaron Dobson and Kenbrell Thompkins have seven drops apiece, which is tied for the NFL lead with five others. Julian Edelman has six drops (tied for eighth in the league).

For the 49ers, who have nine touchdown passes this season, only Anquan Boldin (2) and Vernon Davis (7) have found the end zone after a pass. The Saints have nine different players with a TD reception.

The Broncos have the NFL's best scoring differential (+133). The Chiefs have the NFL's third-best scoring differential (+104).

A.J. Green has accomplished something just two other receivers in NFL history have accomplished. He has 1,000 receiving yards in each of his first three seasons. Jerry Rice, Calvin Johnson, Larry Fitzgerald, Cris Carter and Michael Irvin all are not on this exclusive list. The other two receivers to do this: Randy Moss and John Jefferson. Moss had more than 1,000 yards in each of his first six NFL seasons, twice as many as any other receiver in NFL history.

The Chiefs have faced the NFL's easiest strength of schedule this season. The combined record of Chiefs opponents so far is 30-54 (.357). They have not faced a team that currently has a winning record – the Cowboys and Eagles are the best of this bunch, with 5-5 records.

Andrew Luck has not lost back-to-back games with the Colts. The last time Luck lost back-to-back games was in 2009, when he was a redshirt freshman at Stanford. In October of that year, the Cardinal lost at Oregon State (38-28) and at Arizona (43-38).

Russell Wilson is 12-0 at home in his NFL career. In fact, you have to go back to 2010, when the quarterback was at N.C. State, to find the last time he lost a home game. Wilson was also unbeaten at home at Wisconsin in 2011 (7-0). His last home loss came on October 2, 2010, versus Tyrod Taylor and Virginia Tech (41-30).
