1978 Denver Broncos season
The 1978 Denver Broncos season was the team's 19th year in professional football and its ninth with the National Football League. Led by second-year head coach Red Miller, the Broncos were 10–6, repeated as champions of the AFC West, and made the playoffs for the second straight season.
In the AFC divisional round, Denver lost on the road to the top-seeded Pittsburgh Steelers, whom they had lost to two weeks earlier in the regular season finale at Mile High Stadium; the Broncos had clinched their division title six days earlier with a win over struggling Kansas City, while runners-up Oakland and Seattle both lost and fell to 8–7 with San Diego, two games back with one to play. Pittsburgh went on to win Super Bowl XIII.
Denver was fifteenth in the league in scoring offense, while the Broncos' defense finished second in points allowed and sixth in yards allowed.Offseason
