He mentioned that the idea of unifying the WWE and Universal championships doesn't make sense to him. The WWE Hall of Famer stated:“I don’t agree with unifying the championships because they’re two different shows. It might make things a lot stronger because you’re going to have a full roster of, just say, for instance, all your top-tier talent going to be on that show and they’re all going to be vying for one thing." (H/T:Wrestling Inc)Despite the criticism, Reigns has been focused on his goal. The Tribal Chief will aim to successfully defend his title against Riddle upon his return on next week's SmackDown.
