The 1980 season was the Chicago Bears' 61st in the National Football League, and their third under head coach Neill Armstrong.
One of the victories was on Thanksgiving at Detroit; Chicago entered the Thursday game at 4–8, last place in the NFC Central division, and were trailing 17–3 after three quarters.
With no time left in regulation, Bears quarterback Vince Evans scored a game-tying touchdown that sent the game into overtime.
Then, before a national television audience on CBS, Dave Williams returned a kickoff 95 yards for a touchdown on the first play of overtime for a 23–17 victory over the stunned Lions.
[1][2] Running back Walter Payton once again led the NFC in rushing for the fifth straight year with 1,460 yards; he also had the league's highest annual salary at $475,000.
