Predicting The Next 5 WWE Champions
1. Bobby Roode (SummerSlam 2018)
It looks as though Bobby Roode will follow a similar career trajectory to Shinsuke Nakamura on the main roster. 'The Glorious One' started with a couple of squash victories, and has now moved into a feud with the lowly Dolph Ziggler, much like Nak. He'll inevitably win this match (though WWE will no doubt force Roode to work a heatless 50/50 contest with 'The Show-Off'), before presumably moving on to bigger things.
WWE supposedly have grand plans for Roode, and it's easy to see way. He's a safe, clean wrestler who uses a classic heel style, and his character work has been flawless since arriving. This makes him exactly the kind of wrestler that the company love pushing to the top, but while there's a chance he'll be established as a main eventer long before SummerSlam 2018, Bobby may have to wait for a WWE Title run.
Roode and Nakamura have familiarity from their time in NXT. Those matches weren't perfect, but they came with a strong face/heel dynamic and a clear contrast in characters. This will likely be the case if they wrestle on the main roster too, though Bobby would need to revert back to his natural villainous role beforehand.
