I have three thoughts following the PPV:
1- I really, really hate Cena vs Owens matches. They're bad RoH matches from 2005, just full of moves that should end matches that get kicked out of. Just seems to be a succession of each of them going 'well, I can do this and it'll look cool, then you do that and I'll kick out, then you can kick out of my finisher...' hated it. It was essentially the same match they've had for the past two PPVs.
2- Once again, Roman Reigns was in the match of the night.
3- Brock Lesnar has to win at Summerslam. Has to.
As for Rollins, seeing as Taker vs Brock will sell the PPV to those not on the Network, I'd like to see him up against someone new - Dolph Ziggler would be a cool match, even Rusev or Cesaro.
