#1 Slaying the Beast once and for all will cement Seth Rollins as a top guy

Brock Lesnar has rarely been defeated cleanly since he conquered the Undertaker's Undefeated Streak at WrestleMania. Roman Reigns has a win over Lesnar, but that came with a distraction from Braun Strowman.
The only person to earn a clean victory over the Beast was Goldberg who defeated Brock Lesnar in a minute and twenty-two seconds, reminiscent to what Seth Rollins accomplished at the Grandest Stage of Them All.

If Brock Lesnar decides to call it a career and leaves WWE in August, then a decision to make him lose again in a decisive fashion is the best call Vince McMahon could make.
In all fairness, the chairman of the company has always been in desperate need of a top face in the company ever since Roman Reigns announced his hiatus, and a convincing victory over the Beast Incarnate will cement Rollins as one of the top faces in the company alongside Roman Reigns.
