Ryback sure has an ax to grind.
In a recent episode of Ryback's new podcast, "Conversations with the Big Guy," he talked about John Cena as a "poison" to the wrestling business and accused him of ruining former WWE superstar Alex Riley's career just because he had some sort of personal issue with him.
I will say that based on the dialogue (Alex Riley section aside since all we've ever heard about that has been hearsay), Ryback doesn't seem to understand the business as much as some. He accuses the WWE of pushing John Cena down people's throats and suggests that they instead push the people that the crowd is behind. However, history has shown that those two things are not always directly correlated as Cena has sold tons of merch despite being booed by some of the adult fans in attendance almost everywhere he goes.
