John Cena has put WWE on the map for many of the current generation as a large section of the fan base acknowledges the Leader of Cenation. However, a former star made some bold claims about the Hollywood star.Almost a decade ago, Ryback feuded with John Cena after he turned heel following WrestleMania in New Jersey. The Big Guy was in a program with the Leader of Cenation before other stars in the promotion claimed the top spot.During a live stream on Ryback TV, The Big Guy made some major claims regarding John Cena and how he used to brainwash and manipulate young stars from FCW at his gym to stay at the top in WWE:"I've talked about this before, [John] Cena orchestrated that the FCW talent at the time start working out at his gym, which by the way we're all athletes and we all know how to work out. What he wanted to do was, he brainwashed a bunch of the young guys to look up to him. So that he can manipulate them and politic-wise where people didn't want to challenge him for his spot because he became buddy-buddy with them."He revealed why he kept his distance from John Cena."This is one reason I didn't become a buddy, I got the f**k out of there. I saw what was going on a million miles away and all the guys that he came up, it was all buddy-buddy with them while he still wanted to hold his spot. He knew there was a whole crop of guys that could potentially take his spot. He buddy-buddied up with them where nobody really challenged him."
