5 big similarities between UFC and WWE

#4 Crossovers

They're as common as can be

In the WWE right now there are a parade of superstars with MMA experience, and the number seems to be growing. Brock Lesnar, Ronda Rousey, Sonya Deville and Shayna Baszler have all followed in the footsteps of Ken Shamrock and Dan Severn in making the jump from one to the other. Of course, there are also stars who went the other way.

CM Punk decided to hang up his boots in order to try his luck in the octagon, which is a move that Lesnar himself initially made. Outside of the UFC, we've also seen Batista, Bobby Lashley and Jack Swagger give MMA a try, proving once and for all that you're always going to have guys who believe in themselves enough to cross over into something new.
