#2 Braun Strowman
Roman Reigns and Braun Strowman had one of the most iconic rivalries in WWE throughout 2017. WWE built up two mega-money superstars and gave them an entertaining rivalry which featured stuff like ambulance flipping!
Braun Strowman lost to Roman Reigns at Fastlane 2017, which was his first ever pinfall loss in WWE. Strowman defeated Reigns clean at Payback later that year, and once again defeated him in an ambulance match at Great Balls of Fire.
Strowman remains one of the few superstars who was presented as a level competition for Roman Reigns. Strowman became one of the most beloved superstars during his feud with Reigns, and eventually turned babyface due to his vast popularity.
Strowman has still not won a singles championship in over five years with the company. Hopefully he does so in 2019!
