Peyton Manning comments on 420th TD, Dan Marino

Denver Broncos quarterback Peyton Manning tied former Miami Dolphins and Hall of Fame quarterback Dan Marino on Sunday for second place on the career passing touchdowns list, with 420.

Manning, who grew up as a fan of Marino, spoke about how humbling it is to be mentioned alongside Marino -- with whom Manning has developed a friendship.

Well, Dan Marino, after my dad retired, was my favorite quarterback growing up. I think it's pretty well documented through the years when I've been asked about Dan Marino how I feel about him. I've never felt comfortable kind of being mentioned amongst him. But, a lot of players have caught a lot of those touchdowns, so I'm grateful for all the receivers and the protection I've received along the way. Marino is one of my all-time favorites and he's been very good to me since he stopped playing, and I've really appreciated his friendship.

Marino and Manning both trail Brett Favre, who threw for 508 touchdown passes between 1991 and 2010.

If Manning plays at a high level over the next four seasons, there's a very good possibility that Manning will eclipse Favre's record mark of 508 touchdowns.

Through his first nine games as a member of the Broncos, Manning has thrown 21 touchdown passes, and has only thrown six interceptions. Manning's passer rating of 108 ranks first in the NFL.

Manning will have an opportunity next Sunday to move ahead of Marino, when the Broncos play host to the San Diego Chargers in an AFC West battle.
