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 Tech wide receiver Demaryius Thomas and All-American Florida quarterback Tim Tebow, as well as season-ending injuries to All-Pro linebacker Elvis Dumervil and free agent running back LenDale 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.

Coaching changes On January 13, longtime offensive coordinator/line coach Rick Dennison was hired as the new offensive coordinator for the Houston Texans. On January 14, longtime running backs coach Bobby Turner was hired to the same position with the Washington Redskins, reuniting him with former Broncos' head coach Mike Shanahan. On January 18, the Broncos and defensive coordinator Mike Nolan decided to mutually part ways. On January 23, the following changes were made to the Broncos' coaching staff: Eric Studesville was hired as the new running backs coach. Bob Ligashesky was hired as the new tight ends coach, a position previously held by Clancy Barone, who was moved to offensive line coach. Bob Wylie was named the assistant offensive line coach. Ben McDaniels, younger brother of former head coach Josh McDaniels, became the quarterbacks coach, while Mike McCoy, who previously served as both quarterbacks coach and offensive coordinator, retained his position as offensive coordinator. On January 28, Don Martindale was promoted from linebackers coach to the defensive coordinator position that was previously vacated by Mike Nolan. On February 11, Craig Aukerman, who was previously a linebackers coach at Kent State University, was named the team's defensive assistant. On February 23, the coaching staff was finalized, when Brian Callahan was hired as a coaching assistant.

Firing of Josh McDaniels On December 6, head coach Josh McDaniels was fired, one day after the team's 10–6 loss to the Kansas City Chiefs in Week 13. In addition to the team's sluggish performance (they had gone 5–17 since a 6–0 start to the 2009 season), the videotaping scandal was a factor in his ouster. According to The Denver Post, while Broncos' owner Pat Bowlen did not consider the incident something that merited firing McDaniels for cause, he and others in the Broncos' front office still felt his failure to report the incident was "unforgivable." Running backs coach Eric Studesville was named interim coach that same day.
