Green Bay Packers
Some fans will claim that Mike McCarthy underperformed as the Packers’ head coach. They’ll say that he wasted the prime years of Aaron Rodgers’ career. Despite this, the quarterback won his only Super Bowl ring in McCarthy’s system. That’s why he is their most successful coach of the modern era (via Bleacher Report).
Arguably Matt LaFleur is their worst coach in recent years. Many analysts believed that the Packers were potential contenders in 2021 but they fell short of expectations. Then there were roster problems under his watch with Davante Adams’ departure. He also didn’t stand up to Aaron Rodgers when it was necessary.
