2010 Denver Broncos season

The 2010 season was the Denver Broncos' 41st season in the National Football League (NFL), the 51st overall, the 10th playing their home games at INVESCO Field at Mile High and second and final under head coach Josh McDaniels. The off-season was marked by the draft selections of Georgia Techwide receiverDemaryius Thomas and All-American FloridaquarterbackTim Tebow, as well as season-ending injuries to All-ProlinebackerElvis Dumervil and free agent running backLenDale White. The team failed to improve on its 8–8 record from 2009, and set a new franchise record for losses in a single season, with a 4–12 record, which was their worst record in the post-merger era, and worst in a 16-game schedule. In addition, this was the Broncos' fifth consecutive non-playoff season, which was second-longest such streak in franchise history at the time, behind 1960–1976. The regular season was marked by a videotaping scandal and the firing of head coach Josh McDaniels after 12 games. Running backs coach Eric Studesville served as interim head coach for the final four games.

The Broncos had the league's worst defense in 2010, allowing a league-worst 471 points (29.4 per game) and 6,253 yards. It would be the only season the Broncos lost 12 games for 12 years.
