#3- He almost always wins
Remember when John Cena was going through his Super Cena phase and everyone despised him because he would overcome insurmountable odds to pick up the victory time and time again? Well, that's what's been happening for Roman Reigns since the dissolution of The Shield.
There's a reason why it comes as such a shock when Reigns takes a clean loss. Big deals have been made of his losses against Finn Balor and Braun Strowman. But, they are way too few and far between.
He almost always wins. A prime example would be WWE Fastlane 2017 when he defeated Braun Strowman clean for absolutely no reason at all, ending the Monster Amongst Men's streak of not having been pinned or submitted.
These constant wins have turned the WWE Universe against The Big Dog.
