#1 Braun Strowman

After the main event of WWE Summerslam 2017, there doesn't seem to be a better option for Brock Lesnar's next opponent than Braun Strowman. His manhandling of Lesnar at the start of the encounter was something we have never seen before and cements "The Monster Among Men" as the biggest threat to The Beast Incarnate's reign as WWE Universal Champion.
Now, if it were up to me, I would save this encounter until WWE Wrestlemania 34, but it seems like that main event is set in stone with Roman Reigns being hand-picked to face off against Lesnar on "The Grandest Stage of Them All".
WWE has no plans for these former AEW wrestlers? Here's why!
So, in the meantime, we might as well enjoy seeing how Lesnar and Paul Heyman deal with the monstrous threat of Braun Strowman.
