9. Donovan Dijak
Feast your eyes on Donovan Dijak, who has all the makings of a future singles star in WWE for years to come.
Having made his wrestling debut in 2013, Dijak has accomplished quite a bit in a fairly short span of time. He took the northeast independent wrestling scene by storm before signing with Ring of Honor in 2014, where he won their Top Prospect Tournament the following year and joined Jay Lethal's House of Truth stable.
Dijak received several shots at the ROH World Championship as well as the ROH World Television Championship while with the company. Although he always came up short, he looked extremely impressive in defeat. Sure, he has the size WWE (a.k.a. Vince McMahon) loves, but he can also flat-out go in the ring and is an outstanding athlete.
It was heavily rumored this past summer that he was being courted by WWE, and in September, it was officially announced that he had signed with NXT and was set to report to the Performance Center. As of this writing, he has yet to appear on NXT TV, but it is merely a matter of time before the black-and-yellow brand feels the wrath of the Massachusetts native.
