The veteran suggested that the company should do a double turn during the rivalry between John Cena and Cody Rhodes."I did not listen to a word of this promo. Cody Rhodes' promos are a channel changer for me. They've been a channel changer for a very, very long time. So, I fast forwarded through it. I did not listen to a word of this. And bro, I'm not even going to say I pray because quite frankly, I really don't care what they do, but the reality of the situation is they need to do a double turn. Cody is a freaking heel. Cody has been a heel from day one and maybe if they turn Cody heel, that will force them to reset everything," Russo said.
