#3 Baron Corbin

Everything about Baron Corbin’s push was head-scratching. Not only did he won a Money in The Bank in which Nakamura, AJ Styles, Sami Zayn and Dolph Ziggler were participating but alsio failed to cash it in. Like with Del Rio, this is a guy who was exceedingly tough to get behind due to his lack of charisma and forgettable gimmick. When he cashed in on then-WWE Champion Jinder Mahal, John Cena interfered in the match which cost him the championship.
It was perhaps for the best, as we already had a terrible champion in Jinder Mahal and undoubtedly Cobin's bland character could result in another terrible champion. Although rumours accused him to have lost the contract due to backstage politics.

To add salt to the burn, his feud with John Cena was quickly wrapped up with Cena burying him at a Summerslam opener. Thus, a year’s Money in The Bank and a potential heated rivalry was flushed down the drain.
