When Jay was winning everyone hated him just as much.
He was only likeable when he was consistently losing to Ronnie, whom everyone hated at the time because he kept winning.
Not really, everybody loved Ronnie. He dominated. I think Ronnie had a slight grudge against Jay, because Jay was pretty much given everything, and didn't have to work as hard to get covers, exposure, endorsements. Whereas Ronnie had to work to get to where he was, and everybody had counted him out.
Somewhat like how maybe Kai feels when it comes to Phil, and look who helped/discovered Phil.
