5 potential main events for SummerSlam 2018
4: Brock Lesnar Vs Braun Strowman
Of course, if the WWE go cold on the idea of Roman Reigns toppling Brock Lesnar, then there is always Braun Strowman.
Braun is the most over guy on Raw right now, and his recent victory at The Greatest Royal Rumble surely cements his place as the brand's main babyface.
Braun and Brock have squared off once before, with Brock coming out on top of a disappointing encounter at last year's No Mercy event. Braun's popularity has continued to grow since then though, and perhaps the WWE may finally realise that they could have their next big star in the waiting in Braun Strowman.
This doesn't mean Reigns won't get his hands on the belt eventually, though, it just means that Braun gets the rub of being the one to defeat Lesnar.
