24. Bill O’Brien
Power clearly corrupted O’Brien during his joint tenure as Houston Texans’ GM and head coach. It’s rarely a good idea to entrust both positions to an individual in the modern game because the scale of both jobs are so big. Furthermore, O’Brien answered to himself on a day-to-day basis, which wasn’t healthy. One of most O’Brien’s most striking decisions was to trade star wide receiver DeAndre Hopkins to the Arizona Cardinals.

Hopkins was one of if not the best wideouts in the entire league. Meanwhile, O’Brien had one of the league’s top quarterbacks in DeShaun Watson. O’Brien had a poor relationship with Hopkins but the choice to trade him for David Johnson and a second-round pick was pure insanity. Needless to say, O’Brien’s ineptitude resulted in the Texans firing him after four straight losses early in 2020.
