The WWE held its biggest event of the year earlier this month with WrestleMania 32, and like usual, it was a huge success. A few big things happened during the event, including Roman Reigns getting his title back and John Cena returning to the ring after being out with an injury.

Cena has ventured out into other things, including films, since being a WWE superstar, but don't expect him to go join the mixed martial arts world like some of his fellow WWE stars have done in the past. For one thing, Cena is 38 years old, but on top of that, he just isn't a fan of MMA.

"It's done great to establish itself as a brand, but in comparison with us, it doesn't resonate with me just because I'm a storyteller," Cena said on Larry King Now. "I enjoy the story that we can tell in the ring and like I said, I think we do it better than everyone."

The MMA world and the WWE world will always be linked because, first of all, they both involve wrestling of some sort. Then of course, you have the fact that some of the WWE's biggest stars have gone over to MMA and the UFC. Brock Lesnar fought in the UFC and was actually the heavyweight champion for a little while before going back to the WWE.

CM Punk, despite his advanced age, recently decided to make the move from the WWE to the UFC as well. Punk has yet to actually get in the octagon for a fight due to injuries, but his debut is expected to happen very soon.

Lesnar has said in the past that the business models for the UFC and the WWE are identical but that Vince McMahon is just better at promoting than UFC president Dana White is. Of course, McMahon and the WWE have been around for much longer, but he has a point because White would love to get the UFC to be as big as the WWE is.  

Obviously, the biggest difference between MMA and the WWE is the fact that MMA involves real fighting while the WWE relies more on showmanship, and the vast majority of their fighting is fake. That happens to be what Cena loves about the WWE- he is a showman, and the WWE is the perfect place for him.

There is obviously room for both promotions, but the WWE remains the cream of the crop. WrestleMania 32 set a record for most fans in attendance with upwards of 100,000 people filed into AT&T Stadium, and that produced more than $17 million in revenue just for that one night. The UFC is a growing brand that gains new fans with each pay-per-view, but it isn't close to the WWE just yet. White, however, hopes to one day reach those heights.
