20. Ben McAdoo
McAdoo’s rise and fall were ridiculously quick. After a decent 10-6 first season, things were looking up for the New York Giants. But that optimism disappeared with the speed of an asteroid hitting the ground. In short, they finished the second season with two wins after everything that could go wrong did so.

McAdoo personally mishandled the benching of Eli Manning and overindulged Odell Beckham Jr. Furthermore, he stubbornly held onto playcalling duties instead of doling them out to his specialist coaches. Finally, the failure to shore up the Giants’ defensive line ultimately cost them on the playing field. McAdoo’s bright start was a false dawn for the franchise.
