John Cena's in-ring career ended tonight, his competitive stature. It's rare that people, one, see the end there and then think this is exactly how I want to go out and then get to do it. And that's what John got to do tonight. He had his sort of farewell run this year on his terms and got to do it here in a way tonight that just, it meant the world to him. I could see it in his eyes as he was performing, just having the time of his life.
