#1 Roman Reigns squashes Brock Lesnar!
Could Roman Reigns pull off a Goldberg and destroy the former UFC Heavyweight Champion? Both have the spear that seems to be Lesnar's Achilles heels too.
Being the underdog going into the match, it would be quite a shocker to have Reigns give Lesnar a taste of his own medicine.
It's a highly unlikely booking decision that is also one of the most intriguing ones of the lot. As Reigns vs. Lesnar is reportedly not going to be the main event, an unexpected outcome in the middle of the show would raise the mainstream stock of the grandest PPV of them all.
It also increases the ambiguity surrounding a fragile Lesnar's future while also making Reigns look like an absolute monster. To make it the squash look believable, WWE could bring Lesnar's long history with Diverticulitis into the picture.
The Beast Incarnate could then 'defy the odds' a few months later and return to the Octagon and everything goes as planned in the contrasting yet promotional-wise similar worlds of WWE and UFC.
