It took the Chiefs’ head coach Andy Reid 21 years as a head coach to win a Super Bowl.
Reid earned a Super Bowl ring when he was an offensive line coach for the Green Bay Packers back in 1996—-but, despite winning 10 division championships (6 with the Eagles in the NFC East and 4 with the Chiefs in the AFC West)—-prior to the 2019 season, his only appearance as a head coach in the Super Bowl was in the Eagles’ loss to the Patriots in 2004.
During a similar span of years, the Patriots’ iconic head coach Bill Belichick, has won 17 AFC East championships and 6 Super Bowls (losing in 3 others).
