Generally speaking most people who hold a head coaching position in the NFL are given more than one year to prove themselves within a franchise. The last time that a coach was dismissed after just one year with a club was Steve Wilks with the Arizona Cardinals in 2019.
It is for this reason, among others, that it never made sense for the Dallas Cowboys to say bon voyage to Mike McCarthy. The Cowboys made a big show about their head coach and the Super Bowl ring that he brought to town a year ago, and all of that combined with the global pandemic that arrived just two months after his introduction, along with injuries to some of the team’s most important players, have justified McCarthy’s place at the helm of the team through, at the very least, 2021.
