10. Lesnar Needs An Opponent After Seth Rollins
For a long time, it looked like Brock Lesnar versus Seth Rollins was the SummerSlam main event. However, WWE have pulled the trigger early and booked that match for July's Battleground. It could of course be the case that WWE go with Lesnar Vs Rollins 2 at SummerSlam, but that would mean the feud running for a total of nine to ten weeks. Considering WWE are already having trouble stretching it out in a five week Battleground build, it probably wouldn't be too smart to go with it again in August. It's also doubtful that WWE would switch the title back to Lesnar, when he'll only be gone again after August anyway. So with this in mind, WWE might be looking at having Rollins retain and moving Lesnar on to someone else. That someone else would have to be Kevin Owens, the only other heel in the company at a hot enough level to engage with The Beast.
