5 Controversial Things That Must Happen At WrestleMania 34

#1 John Cena must defeat The Undertaker

The Undertaker's last match?

This shouldn't be happening!

Unfortunately for the WWE Universe, it does look like this match will be happening at WrestleMania 34 and we all know how it's going to end. Sure, some Undertaker fans or even John Cena detractors might believe that WWE will do the right thing and have Undertaker come out on top, that outcome is not best for business.

In fact, what is best for business is for Cena to get arguably the biggest win of his career and knock off The Undertaker at WrestleMania 34. Not only would the win cement Cena's career as the single best run in WWE history, it also finally satisfies the answer of what happens when The Deadman meets The Cenation leader on the Grandest Stage of Them All.

Of course, some are probably wondering how a loss for The Undertaker is best for business and how Cena deserves such a monumental win, but it really all comes down to realism. With that being said and The Undertaker bogged down with both age and a bulk of nagging injuries, it's unfortunate to say that him winning isn't exactly realistic.

In the end, someone needs to finally put The Undertaker down for the last time and there is no better swansong than to lose to the person that was arguably this generation's most popular and most dominant Superstar.

Maybe some will disagree with that notion and are entitled to their opinion, but what exactly does a win for The Undertaker do?
