Zayn has really committed himself as a heel and while he and Styles had a good match, it was far below the quality two guys at that level should have. I think the issue is that working heel negates his natural babyface charisma and he mutes his offense in a way that doesn't suit him. He is capable of playing a heel, sure, and he's really good at the obnoxious heel role. And hey, he has something to do now at least, and he's in the top mix. I'm hopeful that with more time he can make it click, but I still think he's destined to be a babyface long-term. The problem is that historically, there are more cases of undersized obnoxious heels getting chances on top than plucky babyfaces.
