After nearly 13 seasons as the head coach of the Green Bay Packers, it simply took falling in spectacular fashion to the Arizona Cardinals in a game where his team was favored by 14 points to draw an era to an end.
The Cardinals' rookie quarterback, Josh Rosen, completed 11 of his 26 passes and threw for less than 150 yards -- but his team was credited with a 20-17 win. It was the first home loss in December for quarterback Aaron Rodgers since losing to the Houston Texans in his first year as the Packers' starter.
While the writing may have been on the wall that McCarthy's time was dwindling, very few expected the firing to happen during the season.
