McGregor went too far with Cena, people who are insecure about WWE crossing with MMA won't understand but even if Cena is a WWE guy he's actually a great person. Does lots of charity work with veterans and has done more things for make a wish foundation than any other athlete, make a wish foundation is for terminally ill children if you didn't know. Fair enough if he disses all those fake fighters talking shit but Cena is always super respectful even though it's pretty clear he doesn't like the sport.
