#3 Samoa Joe squashes Rey Mysterio again
Rey Mysterio faced Samoa Joe at WrestleMania for the United States Championship, but due to time constraints, the match didn't get an adequate amount of time.
Rey again scored a pin-fall over Samoa Joe and earned his shot at the title at Money in the Bank. Rey's son Dominic may have also signed a contract with WWE, and is expected to be present alongside Mysterio.
Samoa Joe could use Dominic to his advantage as a distraction for Rey Mysterio. He could attack Dominic and choke him out to create a diversion for Rey.
This diversion gives him a chance to finish a distracted Mysterio in a matter of minutes quickly.
#2 Brock Lesnar shows up
Given Brock Lesnar's schedule, it's highly unlikely that he appears before the Saudi Arabia event next month, but that's what makes it a shock when he shows up at Money in the Bank.
Brock is rumored to face either Seth Rollins alone or both Rollins and AJ Styles for the WWE Universal Championship.
If the latter is true, Brock might interfere in the match and lay out both of them. It would give him a proper reason to get back into the title picture.
