10 WWE NXT Main Roster Call-Ups That Must Happen In 2019

10. Matt Riddle

Matt Riddle's entire NXT run should really be the short sharp shock his TakeOver: War Games II debut was.

The 'King Of Bros' blew through the affable Kassius Ohno in a match victorious as much for Triple H's anti-promotion of it was Riddle's exhilarating offensive flurry. 'The Game' had shrewdly taken the contest off the table earlier in the week, irritating many that were excited to see his supershow bow.

This fan-friendly bait-and-switch worked a charm in ensuring audiences weren't angered with the rapid-fire appearance, and also highlighted how happy they were just to even get a glimpse of the brand's possible next big thing.

A Riddle squash as a developmental curtain-jerker was a lot of fun. A Riddle squash as a main roster headliner could fundamentally change the game.

Nobody is set up to beat Brock Lesnar anymore, including the man that actually probably will in 2019. Braun Strowman has to topple 'The Beast' sooner or later just as Roman Reigns did back at SummerSlam, but like 'The Big Dog' the window of opportunity on actually utilising the result has already slammed shut.

This Riddle doesn't require a particularly complex solution. A "Bro!" and blow to Brock along with a flash Universal Title switch would be one of the most powerful put-over's in company history.
