Just the opportunity to go into it. John and I have a lot of history, from him costing me the Money in the Bank briefcase you know, our match at SummerSlam. We've wrestled a billion times. There's always a history there. Man it would be the coolest thing ever if I was one of the guys who does not work there right now but got the call to be a part of the tournament. Not to win the tournament, but let me go fight Gunther, because I've never been in the ring with him. It would be a hell of a brawl. We could beat the living sh** out of each other. It'd be really fun. It would be awesome. I would love that."Baron Corbin is not in WWE right now, but could return to face John CenaWhile Corbin is not a part of WWE, the star has been a top name there in the past. He was let go earlier, but he has wrestled almost every top name in the company.With the history between Cena and Corbin, it would be interesting for him to return to be a part of the tournament for one night only and give the crowd a shock as well with that moment.It remains to be seen what happens.
