Peyton Manning and the Denver Broncos sit atop the AFC West with a 7-3 record, after defeating the San Diego Chargers 30-23. Manning threw for 270 yards and three touchdowns in winning his 148th regular-season game starting at quarterback.

In his 15th NFL campaign and first season in Denver, the four-time NFL MVP has quickly acclimated to his new teammates and developed a strong chemistry with his receivers.

Manning has completed at least 70 percent of his passes in six straight games, the longest streak in NFL history (minimum 20 attempts). Through Week 11, Manning ranks second in the AFC with 2,975 passing yards and is first in the conference with 24 touchdown passes. Manning fell short of becoming only the third player in NFL history to reach 3,000 yards in the first 10 games with a team.

"Peyton Manning will beat you with experience," says CBS analyst and former NFL quarterback Phil Simms. "He's been in control of offenses for so long. He knows the style of offense that is going to work in the NFL. He has a group of plays that he knows is going to work in the NFL. He knows them better than anybody. That is a great head start on most NFL teams. The Broncos already have it built in. It's just about them going out there and executing."

Manning, who became the NFL's all-time leader in 300-yard passing games (69) this season and now has the most come-from-behind victories in the fourth quarter or overtime (48) of any quarterback since 1970, continues his rise up league's record books. On Sunday, Manning (423) surpassed Pro Football Hall of Famer Dan Marino (420) for the second-most touchdown passes in NFL history. Brett Favre holds the record for touchdown passes in NFL history with 508

"He has made a tremendous impact by playing the quarterback position at such a high level for so many years," says CBS Sports' NFL TODAY analyst Dan Marino.

Manning (148-70-0) surpassed Marino (147) and tied Broncos Pro Football Hall of Fame quarterback John Elway (148) for the second-most regular-season wins as a starter in NFL history. Brett Favre is the all-time leader with 186 regular-season wins as a starter.
