1. Vince McMahon
AJ Styles biggest problem in WWE is going to be Vince McMahon. Styles just isn't Vince's type of guy, he's very much a Triple H signing. The same was true of Kevin Owens, with reports suggesting that Vince McMahon and producer Kevin Dunn just didn't get K.O. Following those reports, Owens' push stumbled. The worry for AJ Styles is that the same situation may play out. Hunter brings him in and gets an initial push going, but then Vince and Dunn decide it isn't right. The fact is, Vince McMahon probably has no idea of who AJ Styles is. He won't have seen any AJ matches or be aware of his accomplishments. When he first sees him this weekend at the Royal Rumble, his first impression is probably going to be the size issue. It remains one of Vince's obsessions, and he could end up writing Styles off as just another guy who doesn't fit the WWE mould.
