He's got a better physique than Daniel Bryan, who despite being a vanilla midget had an incredible in ring acumen. Neville is missing that indescribable factor, that "I don't know what" or "it" factor that made Bryan such a huge star, basically charisma.
Reigns has the body of a god but the charisma of a dung beetle. Bryan looked like a goat but you wanted to believe in him. There was this earnestness in his promos that made you want to root for him. I don't feel that with Neville.
He's a bit awkward on the stick, but so was Bryan. Neville hasn't discovered that one thing that really gets him going. For Bryan, it was the yes chants. Neville in his current state has the tagline "man that gravity forgot" that feels a bit pretentious.
Until he discovers that missing factor, he's a highlight real midcard guy. I could see a late career title victory, but he just doesn't have that charismatic pass for what he lacks in look. Christian had enough charisma to overcome his look, but ultimately Vince would never take a chance on him. It took the two world title era to give Captain Charisma a world title in WWE, and that time has passed.
I like Neville, I preferred it when he had a first name. He's got the indie pedigree, the NXT call up, he has all the potential, but he has a lot of the stereotypical flags that WWE traditionally does not push.
Of everyone who has come up through NXT in the last two years, I'd say he has a chance, but he's far behind guys that are yet to be called up like Balor or even Apollo Crews, let alone the litany of guys on the main roster who could be world champion.
I want to stay optimistic for Nevile, but he's got a lot going against him.
