At Night Of Champions, it was Triple H v. John Cena v. the WWE Champion Randy Orton for the WWE title. Randy Orton was in a world of trouble near the end of the match because John Cena had the STF locked on him and at the same time, HHH had the Sharpshooter locked on him.
When the champion finally tapped out, the ref was confused which submission maneuver was causing Randy Orton to tap out. A few seconds later, Legacy came out and attacked Cena and HHH.
Orton was able to hit the RKO on Cena and then pinned him, allowing Orton to walk out still champion.
The following Raw, the special host Shaquille O'Neal made a Beat the Clock tournament featuring Jack Swagger, HHH, Mark Henry, John Cena, and MVP to determine who would face Randy Orton at Summerslam for the WWE Championship.
John Cena won and will face Randy Orton for the WWE Championship at Summerslam.
John Cena should have a lot of hype and momentum because he will have the fans, but he needs to hope that Leacy will not interfere and cause a disqualification.
If he comes out worrying that Legacy will interfere he will most likely lose the match. And he cannot let the Viper gain lots of momentum because it will be very hard to stop the champion.
I think that Cena will find a way to win. Either way, they are both very talented superstars and it will be a great match.
