#4 A Jorge Masvidal-Ven Askren reference
WWE loves pop-culture references and any reference that is basically trending. Obviously, the UFC 239 PPV saw a historic knockout, as Jorge Masvidal put away the previously undefeated Ben Askren in five seconds - hitting a running knee to the face before landing an extra shot on an already unconcious Askren.
Not only did that shoot Masvidal's stock up, but it got the sports world with all eyes on UFC. It's clear that WWE usually likes taking a page or two out of the UFC's book (and the UFC occasionally does the same from WWE).
Since WWE usually want in and to get people talking, this was likely done as their version of Masvidal-Askren. We do admit that if so, it was quite funnily done and more importantly - well done.
However, few things can cause the shock and impact that the Masvidal knockout did.
