#3 Otis winning Money in the Bank
One of the Superstars who suffered the most from the lack of live fans has been Otis, who thrived off the reactions he was getting. That put a dampener on his WrestleMania moment with Mandy Rose. However, WWE was high on Otis and he ended up winning the Money in the Bank contract, probably because Vince McMahon thought it would be funny.
But once the dust settled and the former Heavy Machinery star was in line to become a world champion in WWE, the company made next to no efforts in molding his character to become more serious. Instead, the briefcase was used as a comedic prop and had ham sandwiches stored in it.
Since his shocking victory at Money in the Bank, Otis lost everything he had in WWE. Mandy Rose and Tucker were traded to RAW, with the latter turning heel on him and costing him the Money in the Bank contract at Hell in a Cell. The Miz defeated him for it, restoring some hope for a successful cash-in this time.
WWE should have simply focused on the love story between Otis and Mandy Rose, as well as Heavy Machinery as a tag team. The Money in the Bank briefcase was nearly wasted for another year just for a single gag, with other more exciting options who could have benefitted from the instant push more than Otis.
