In 2019, the Cowboys finished 8-8 and fired their head coach, only to end up at 6-10 in the 2020 season. Prior to that, the last time the Cowboys changed their head coach after an 8-8 season, they ended up with a 5-11 record the next year. Chan Gailey coached the Cowboys to an 8-8 record in 1999 and was then replaced by Dave Campo, who promptly took the Cowboys to 5-11 in 2000.
A remarkable synchronicity of events, even if it is probably meaningless.
But outside of that piece of Cowboys trivia, what does the historical record tell us about the performance of 6-10 teams the following season?
