PASSING YARDAGE: Another of the biggies. Manning has 4,522 yards and is on pace for 5,565. Drew Brees holds the record with 5,476, set in 2011. Manning is throwing for 347 a game this season and could break the record by throwing for 29 below his average each game. This one is a bit tricky, though, mainly because the Broncos' three remaining opponents — San Diego, Houston and Oakland — are a combined 12-27. The Broncos will probably try to rest the 16-year veteran if they get way ahead. Working in favor of setting the record, however, is that the Broncos have only a one-game lead over Kansas City in the AFC West and New England for the No. 1 playoff seed, so, at this point, they need to win all the games.
COMPLETIONS, ATTEMPTS, PASSER RATING: All these are stretches, especially if Manning doesn't play out the entire season. Then again, he went 39 for 59 with a 107.8 passer rating last week, and a few more outings like that will definitely put him in the mix. Through 13 games, Manning has 366 completions, leaving him 102 short of Brees' record in 2011; Manning's 539 attempts are 188 shy of Matthew Stafford's mark from last year. Meanwhile, Manning's 114.5 passer rating currently ranks fourth all-time. The record is 122.5, set by Aaron Rodgers in 2011.
TOTAL POINTS: The 2007 Patriots hold the mark with 589. The Broncos are the first team to score 50 or more three times in a season since the NFL merger in 1970. The result: They've scored 515 with three games left. It means they have to average only 24.6 the rest of the year to break the mark. They've been held under 30 only twice this season — by San Diego in Week 10 and Kansas City in Week 11.
DOUBLE-DIGIT TOUCHDOWNS: Actually, the Broncos have already broken this record, becoming the first team with four players scoring 10 touchdowns or more. But they could make it five. Eric Decker, who scored four TDs in a win over Kansas City two weeks ago, needs two more to join Knowshon Moreno, Julius Thomas, Demaryius Thomas and Wes Welker in double digits.
