Q: Context_1 : The Denver Broncos season was the team's 35th year in professional football and its 25th with the National Football League. The season would be noted for being the final year that Wade Phillips was head coach. Context_2 : The Denver Broncos season was their 40th season in the NFL and 50th season overall. The Broncos matched their 88 regular season record from 2008, but did not make the playoffs. The Broncos welcomed many new defensive players signed during free agency, including veteran Eagles safety Brian Dawkins. This was their first season without head coach Mike Shanahan since , as he was fired on December 30, 2008. On January 12, 2009, Denver hired former New England Patriots' offensive coordinator Josh McDaniels as their new head coach. At the time of his hiring, McDaniels was the youngest head coach in any of the four major North American professional sports and the fifth-youngest NFL head coach ever, though less than a week later the Tampa Bay Buccaneers named the even-younger Raheem Morris as their head coach. Context_3 : The Denver Broncos season was the team's 26th year in professional football and its 16th with the National Football League (NFL). Despite finishing with an impressive record of eleven wins and five losses, the Broncos failed to make the playoffs. The Broncos were coming off a loss to the Steelers in the divisional round, and were picked by many to make the Super Bowl at the end of the 1985 season. The Broncos would start out well, as they started 6-2 and 8-3. However, two losses in overtime to arch rival Los Angeles resulted in the Broncos needing to win their final two games of the season to try to sneak into the playoffs. They did just that, beating Kansas City 14-13 and Seattle 27-24. However, even though the Broncos finished 11-5, they failed to reach the playoffs by virtue of a tiebreaker with the New England Patriots. The tiebreaker was based on the teams' common opponents record; and the Patriots beat the Broncos in that category by finishing 4-2 against the Raiders, Seahawks, Dolphins, and Colts, while the Broncos finished just 3-3 against the same four teams. The 1985 Broncos are one of two teams in NFL history since the 1970 merger to end the season with eleven or more wins and not qualify for the playoffs. The other is the 2008 Patriots. Context_4 : The 1984 Denver Broncos season was the team's 25th year in professional football and its 15th with the National Football League (NFL). The team finished with its then franchise best record of thirteen wins and three losses and were champions of the AFC West. The season ended in a heartbreaking Divisional Playoff loss against the Pittsburgh Steelers. This would be the final season for Tight End coach Fran Polsfoot, who died in April 1985. Context_5 : The 1999 Denver Broncos season was the team's 40th year in professional football and its 30th with the National Football League (NFL). After winning its second consecutive Super Bowl with a win over the Atlanta Falcons in Super Bowl XXXIII in Miami, the team suffered the retirement of Super Bowl XXXIII MVP quarterback John Elway during the off-season. Elway had spent his entire career with the Denver Broncos, and much of the focus in the weeks leading up to the season centered on the void left by Elway's departure. Head Coach Mike Shanahan announced that third-round 1998 draft pick Brian Griese, son of Miami Dolphins Quarterback Bob Griese, would take the reins of the offense, passing over veteran and credible back-up QB Bubby Brister. Context_6 : The 1981 Denver Broncos season was the team's 22nd year in professional football and its 12th with the National Football League (NFL). The 1981 season depicted Denver trying to improve on their 8-8 record in 1980. They did improve on their record, finishing 10-6. However, they would miss the playoffs by virtue of their head to head loss to the Buffalo Bills during the season. After a very fast 8-3 start, Denver would lose 3 of their final 5 games, including a critical loss to the Cincinnati Bengals in week 12. Denver would finish 8-0 at home, but a 2-6 road record proved to doom the Broncos at season's end. Context_7 : Patrick Dennis Bowlen (born February 18, 1944) is the majority owner of the Denver Broncos of the National Football League (NFL). The Bowlen Family, including his two brothers John Bowlen and Bill Bowlen, and sister Marybeth Bowlen, purchased the team from Edgar Kaiser in 1984. He served as the Broncos CEO from his purchase of the club in 1984 until July 2014, when he stepped down as Broncos' CEO due to the onset and progression of Alzheimer's disease. Context_8 : The 1982 Denver Broncos season was the team's 23rd year in professional football and its 13th with the National Football League (NFL). The Broncos played only nine games this season, owing to the strike imposed by the National Football League Players Association (NFLPA). The Broncos were looking to improve on their 10-6 record from 1981. But due to many injuries plus the strike, the Broncos only won 2 games, while losing 7, their worst record since 1971 as well as their first losing season since 1975. This was also their first season with below 3 wins since 1964. The Broncos only won 1 home game the entire year, against reigning Super Bowl champion San Francisco. Their only other win was against the Los Angeles Rams. The Broncos went winless against AFC foes in 1982. All of their AFC foes were their own division rivals. Context_9 : The 2008 Denver Broncos season was the franchise's 39th season in the National Football League, the 49th overall and the 25th under the ownership of Pat Bowlen. The Broncos improved from their 79 record from 2007, but failed to make the playoffs with an 88 record. Context_10 : The Denver Broncos season was the team's 45th year in professional football and its 35th with the National Football League. Head coach Mike Shanahan guided the Broncos to a 10-6 record, finishing 2nd in the AFC West. The Denver Broncos season ended in defeat to the Indianapolis Colts 49-24 in the Wild Card Playoffs. fact_1 : The 2008 Denver Broncos season was the franchise's 39th season in the National Football League, the 49th overall and the 25th under the ownership of Pat Bowlen. fact_2 : He served as the Broncos CEO from his purchase of the club in 1984 until July 2014, when he stepped down as Broncos' CEO due to the onset and progression of Alzheimer's disease.
