#2 To rekindle a feud with Roman Reigns
Perhaps the best feud of Braun Strowman's career thus far has been with Roman Reigns. Both men are powerhouses and they took each other to the limit during the feud. One can even argue that Braun Strowman hasn't looked hotter since, than when he was putting on those great matches against The Big Dog.
I really do think that Braun Strowman and Roman Reigns could have yet another great feud on SmackDown Live and the audience will be invested in it. Not only has a certain amount of time passed to make the feud fresh once again, Roman Reigns seems to have lost a lot of momentum feuding with The Bludgeon Brothers in a storyline that started great but doesn't seem to be going anywhere at the moment. If Brock Lesnar remains on SmackDown, these are the two men that he should be wary of, who're both aiming for his throne.
Braun Strowman himself has lost a great deal of momentum ever since he took the pin against Seth Rollins in a match that Rollins decisively won. Were he to pin Roman Reigns, the audience would really buy into the monster again.
