#1 Shouldn't: Strowman losing at Hell in a Cell
Well, Braun Strowman is all set to battle it out with Roman Reigns for the WWE Universal Championship at Hell in a Cell. And given the recent report of Cagesidesseats.com, rumours of him losing at Hell in a Cell has cropped all over the internet.
Strowman was over as a babyface among WWE fans, and a loss at HIAC plus his recent heel turn would destroy all his momentum.
Thus, a rumoured loss for The Monster Among Men at HIAC should not happen.
