Cena takes a "The Raven 2" esque approach to wrestling.
They're like "Hey Cena, we thought up a great gimmick for you, you should do this"
And he's like "**** THAT IMMA BE MYSELF"
Can you imagine Cena in the Attitude Era and before?
"Cena, we want you to be an evil friar that hits people with wine bottles behind the refs back"
"But I'm not a friar and I don't like wine"
