...if Lesnar not only retained, but ended up dominating Reigns in a similar fashion to how badly Cena got dominated at last year's Summerslam?
I mean, I know there's rumors that Brock might retain at Wrestlemania now (and I'll believe that one when I see it), and in no way do I think it would be a good idea to have him rag-doll Reigns around like this even if they were already backpedaling on Reigns' push (I don't think it was a good idea to have Brock rag-doll Cena around the way he did either, but that's another topic), but it would still be surreal seeing Reigns get his ass whooped that bad. Now Heyman could brag about how Lesnar has the most dominating performances for both a Summerslam AND Wrestlemania main event to his name. (Although because it's Wrestlemania and all, it will probably be best if Reigns was allowed to get in a little more offense than Cena did, something closer to how Cena fared at Night Of Champions but with Reigns still losing.) Maybe Reigns could then start some sort of path of redemption where he realizes that as hungry as he was, he wasn't quite ready just yet to take on someone like Brock and now he has to begin his path to the world championship all over again. Also, fans might actually respect Reigns more in a way if he took the fight to Brock and went down swinging like a man since it would humanize him a bit more.
Total hypothetical scenario that has about a 1% chance of happening, but it's an interesting and funny to think about nonetheless.
