#4 WrestleMania rematches
There are a handful of matches on the WrestleMania 36 card that, while good and intriguing, would be made so much more impactful if a crowd was in attendance to see it happen.
WWE has a history of trying again at SummerSlam with bouts that didn't quite work out at 'Mania, and we wouldn't be at all shocked to see them go down this route with something like Brock Lesnar vs Drew McIntyre or Edge vs Randy Orton.

Many fans fear that quite a few heels could walk away with big wins at 'Mania courtesy of there being no fans in attendance to react to it, and if that's the case, SummerSlam is the place for them to reverse that.
We understand that there's a whole lot of 'ifs and buts' featured in this scenario, but Brock Lesnar vs Seth Rollins taught us anything, its that SummerSlam can be a useful tool for pressing the reboot button if it doesn't work out as you'd planned the first time.
