WWE SummerSlam 2017: 5 things that should not happen at the PPV

#4 Brock Lesnar retains

Brock Lesnar captures the Universal title at WrestleMania 33

Allowing Brock Lesnar to retain the Universal title this Sunday would be a horrendous mistake. Lesnar has more star power than anyone in WWE not named John Cena, but the circumstances surrounding him are all saying that now is the time for him to drop the belt. And if he doesn't, it could be catastrophic for RAW.

The hype surrounding a potential Lesnar vs Jon Jones UFC fight is picking up quickly. "The Beast Incarnate" reportedly re-entered the USADA drug testing pool recently, meaning he is seriously considering another UFC fight. And that interest was confirmed by Lesnar responding to Jones' challenge when he said, "be careful what you wish for."

Yes, Lesnar has fought for UFC before while still being under contract with the WWE. But he didn't have RAW's most coveted prize in his possession at the time. Plus, a part-timer holding the top championship on a brand gets old pretty quickly with or without the threat of leaving for UFC. It's time for a change of pace.

Any one of Lesnar's opponents in the fatal 4-way would make for an amazing next Universal Champion. The only wrong decision would be to let Lesnar retain.
