#5 Matt Riddle
Matt Riddle is getting all the focus he is right out of the gate for a reason. At some point in 2019, it's going to be his NXT, and unlike many alumni from the yellow brand, a bright future on the main roster is likely to await him after he graduates from the Performance Center and Full Sail.

He's biding his time with Kassius Ohno for now, but he's surely going to enter NXT Championship contention by the middle of next year. He may well be the one to defeat Tommaso Ciampa, given how much Johnny Gargano has been struggling and the odd turn his character has taken.
Either way, he will almost certainly be NXT Champion by this time next year. He didn't worm himself into the TakeOver: War Games II card for no reason. The NXT brass is super high on him. That is certain.
