For the last couple of months the company has tried hard to get Brock back over as a heel and attempted to capitalize on the fan backlash of Lesnar not being around. As a friend of mine said the "WWE Universal Championship picture this year has been incredibly boring & lackluster." I understand that they wanted to erase CM Punk from the history books but the one thing I don't understand is that if Brock is gone after Summerslam and likely will not comeback anytime soon why let him get the record. Then again that's beside the point because right now their is only one person who should carry the Universal Title in the latter half of the year.
In my opinion the only way that they get some interest back in the title is to have Braun cash in on Brock before he leaves the company to get someone the fans actually want to see topple the "Beast" topple him. I don't hate Roman Reigns but they have done nothing since his loss at Greatest Royal Rumble to make him seem important or worthwhile for a title opportunity. Right now to quote a certain former manager Roman is "plainer then a plate of piss" and has done nothing to stick out and needs to stay away from the title picture for right now.
Looking up and down the WWE roster I think Braun is the only person that should defeat Brock for two reasons. First reason is that it would provide a full circle feel for the feud between these two men after how last year's Fatal Four Way went and similar to the Goldberg/Brock thing it would hopefully allow them to erase their poor first encounter. Secondly imagine how hot Braun would be after he defeated Brock to win the Universal title in my book he would be Cena levels of bullet proof. This way you could now have Strowman redo feuds or jump into new feuds with names that could've never fought Lesnar for one reason or another. Overall the easy answer is that Braun should cash in before Brock leaves, but I will take it a step further to say that Braun needs to cash in at Summerslam to save the event.
