both Jericho and Balor have said the same thing upon coming to the WWE, Jericho talked about how after his first 6 months he thought he was doing OK until Vince and JR sat him down and basically broke down what he was doing wrong
HHH makes that analogy about being successful elsewhere and then coming to the PC and the WWE and doing it "their way" and he's not entirely wrong
People are freaking because they didn't strap a rocket to AJ and send him right to the top of the card, im sure HHH and Vince know AJ is talented, but there is a lot to get used to in the WWE as opposed to any other company
