#3 Andrade

Ever since arriving in WWE, Andrade has been considered the future of the company, and going up against a top babyface like Kingston at SummerSlam could be his opportunity to prove it. With Zelina Vega by his side, it's clear that El Idolo is a future WWE Champion, and while rising through the ranks of SmackDown Live could be a good story, he's ready for the main event scene now.
This is the most unlikely event on our list, but given the great character work he does along with his incredible athleticism, this would be an absolute barn-burner, and could steal the show in Toronto.
Look who just shut down all of Tony Khan's critics! More HERE.
WWE clearly have plans for the former NXT Champion, but with so much talent on the roster, they need to start building up his momentum soon, and while losing to Kingston may not be the best way to do that, it would prove that he's a main event level player.
