John Cena was the face of WWE for well over a decade.
He's a 16-time world champion and is one of the most recognisable superstars in history.
Love him or hate him, you can't deny Cena was a top star and he's still a massive draw whenever he returns to the squared circle.
It's long been known that Vince McMahon is a massive fan of him - after all, he wouldn't have been the face of the company if that wasn't the case.
But why did Vince put so much trust in Cena? Well, according to Jim Ross, who has recently been speaking on the Grilling JR podcast, there were a number of important reasons.
"Passion, John's passion was overwhelming," Ross told the podcast of why Cena was picked to be the face of WWE, per Wrestling Inc.
"His dedication to his craft was overwhelming. I don't know that anybody had any doubts that I talked to.
"I don't think there were any massive apprehensions because we knew we were going to the right guy."
JR also noted that Cena was so reliable as a top star because he would 'never say no' and did everything he was asked to do - and more.
"Here's the thing about this, John was a guy who never said no, he worked his ass off for seven days a week or 10 days a week if there were 10 days in the week. He loved what he did.
"His record for Make-A-Wishes, granting wishes for terminally ill children, nobody is even close. That was the kind of guy he was, he would never turn anything down that's the kind of guy he was.
"He did everything he was asked to do. Because he was such a big star, the people that were asking knew John liked to do these and he won't say no."
Ross also revealed that WWE always had complete confidence in Cena and never had any issues with his physical status.
"All of a sudden they get the top talent who isn't going to say no so they're silly not to ask him. He didn't turn anything down but the cover," JR continued.
"He was just always there, we didn't have any issues of if John was injury-prone. He worked all the time, worked a hard style.
"The point being is at no point did we lose confidence that John Cena wasn't going to hold up."
Whether you loved him or hated him as a wrestler, there's no denying that Big Match John carried WWE for almost 15 years and it seems Vince never doubted him - not even for a single moment.
