The Broncos' defense began the first five games of the 2006 season allowing only one touchdown—an NFL record that still stands, ESPN commentator and Super Bowl winning QB Joe Theismann gave that 2006 Denver Defense the name Bad Blue on Monday night football Broncos vs. Ravens but the team struggled down the season stretch. Plummer led the team to a 7–2 record, only to struggle and be replaced by rookie quarterback Jay Cutler. Cutler went 2–3 as a starter, and the Broncos finished with a 9–7 record, losing the tiebreaker to the Kansas City Chiefs for the final playoff spot. Cutler's first full season as a starter in 2007 became the Broncos' first losing season since 1999, with a 7–9 record.
