Some players blatantly become scapegoats because they have inept coaches. Manning became a high-profile casualty when Ben McAdoo decided to stamp his authority. The head coach took the legendary Giants quarterback out of the limelight and installed Geno Smith as the starter.
McAdoo attempted to cast the blame for the Giants’ malaise on the two-time Super Bowl winner. In the end, it didn’t work out as they went 2-10 before he lost his job in 2017. If he spent as much time coaching as he did applying hair gel, the team might have done better (via SBNation).
