#1. Matt Riddle
Matt Riddle has arguably had the most stunning main roster debut by an NXT star since the debuting Finn Balor's magical Universal Championship win on Raw in 2016, defeating AJ Styles. In his own words, he felt like he was on 'cloud 24'.
Vince McMahon and Bruce Prichard evidently have a lot of faith in Riddle. The former MMA star has had a dream debut and looks set to feud with Baron Corbin.

Despite fans' dislike for the King, Corbin has been one of the cornerstones of WWE television in recent times. He is a top star that people legitimately hate and tune in to see him get beaten inside a WWE ring. Riddle's involvement in a rivalry against a top-tier heel that he's likely to win will raise his status as a star.
Matt Riddle has been known to make bold statements. However, he can stand by his words inside the squared-circle.
Riddle's success will largely depend on his in-ring exploits. WWE will present him as a fighter, and it'd be unsurprising if they put the Intercontinental Championship on him sooner than later.
