#1 Roman Reigns

If Roman Reigns is going to win the Universal Championship at SummerSlam then it is highly likely that Kevin Owens will cash-in the Money In The Bank on him (as we previously assumed that he will win the Money In The Bank briefcase).
Rumors are strongly suggesting that 'The Big Dog' will defeat Lesnar at SummerSlam to become the next Universal Champion. He is chasing for the title from this year's WrestleMania but he failed to marmalize Lesnar but this can finally happen at the Biggest Party of the Summer.
Why this match can happen: If the Prizefighter will cash-in the briefcase on Reigns then there is no doubt that we will see a feud between these two superstars for the title in future.
In this way, Owens will get the title whereas Roman will get sympathy from the fans and this might become beneficial for the WWE. Because of having a heel persona, the fans will probably cheer Roman Reigns instead of Kevin Owens.
