Answer
The Broncos had not won a division title since 2005, when they went 13-3 and won the AFC West. In 2011, they finished the regular season with a 13-3 record again, but this time they lost in the AFC Championship Game to the New England Patriots. Tebow led the Broncos to their first playoff victory since 2005 when they defeated the Pittsburgh Steelers in the Wild Card round.
