He's going to come out of a NXT run better than most. Dude wasn't really getting booked anywhere of note but PWG (which is wild since PWG is usually the sign of being a top indie guy that gets booked everywhere) before signing & now he'll be getting a ton more bookings if he doesn't sign somewhere else that limits his outside stuff.
He's honestly not anything special which is why his push in NXT was wild to me. He's a "big" guy that can move but he ain't moving like a Keith Lee, he ain't a big power guy, & he doesn't have crazy charisma
