#4 Braun Strowman
Braun Strowman has been one of the most over Superstars at the moment as the 'Monster Among Men' has gained everyone's attention with his performances of late. His feud against Roman Reigns was a big turning point in his career as it elevated both the Superstars.
Braun is currently holding the Money In The Bank briefcase and many expect him to cash in on Brock Lesnar or Roman Reigns at SummerSlam. But, a monster like Braun doesn't need a briefcase to look strong and by now, he should have held the WWE Universal championship at least once.
But, all he got was the Raw tag team championships which he won at WrestleMania 34. Braun has the charisma to be over with the fans and the WWE should book him in the right direction and hand him the title before he becomes stale.
