#2. The Money In The Bank is cashed in and a new champion is crowned
No one is happy to see Brock Lesnar face Roman Reigns for the fourth time. Roman Reigns might not be popular with the fans, Brock Lesnar also suffers the same fate because of being a champion for more than 500 days and defending his title only 10 times. This has declined the credibility of the Universal Championship. WWE creatives want Roman Reigns to be the person to dethrone Brock Lesnar and it was set to happen at WrestleMania 34, but WWE avoided it due to backlash Roman would have suffered. Thus, in order to avoid a repeat of WrestleMania, WWE must have something major planned.
The fans know they are again going to suffer the same fate. That's where Money in The Bank comes into play. While MITB is currently held by Braun Strowman, he has to defend it against Kevin Owens. WWE has planned Kevin Owens Vs Roman Reigns at Hell in A Cell; that means we are seeing Kevin Owens becoming Mr. MITB and cashing it on victorious Roman Reigns in the main event.
Kevin Owens is the best heel on Raw and making him the Universal Champion is money. Even if Braun Strowman manages to defeat Kevin Owens, expect him to cash in and wreck Roman Reigns after the match. One way or another, we will have a new Universal Champion at the end of SummerSlam... and his name will not be Roman Reigns.
