#2 Drew McIntyre
Drew McIntyre is regarded as one of the top guys of the Red Brand. The Scottish Psychopath teamed up with Shane McMahon to face the team of Roman Reigns and The Undertaker at Extreme Rules.
Currently, Shane is slated to face Kevin Owens at SummerSlam and thus, it will be interesting to see if McIntyre gets an opponent at the Biggest Party of the Summer.
Although McIntyre had an ordinary run in his first tenure with the WWE, his second run has been exceptional. He won the NXT Title in the developmental brand and he has established himself as a top heel since making the main roster return last year. Following his main roster return, he has decimated several titanic names of the company.
On potential, the former NXT Champion has all the attributes to be the Universal Champion and he could be a big threat to Lesnar.
Considering the pair has never embroiled itself in a feud, it could be intriguing for the WWE Universe to witness. Moreover, the Scottish Psychopath could be a credible challenger to dethrone the Beast Incarnate.
