Sure. It's great that some people know more about their profession than others. However, you directly linked his likability to his knowledge to promotions who are in the minority with his audience. That has absolutely nothing to do with his character or perception.
I personally don't like a dude who is at that level and doesn't try to be more knowledgeable or better at his job. And I can't feel bad for him when doesn't get pushed because he sucks in the ring and the reason he sucks is probably related to not trying to be knowledgeable or getting better at his job. And I don't like him because I don't think he's good at wrestling or talking, and that he's whiny about not getting his shot when he hasn't done anything to show he deserves anything more than he has.
I'm not talking about fans. I'm talking about Zack Ryder/wrestlers in general. Being unknowledgeable is one thing. Going out of your way to stay that way is stupid.
