His first one was better because it was the first promo where Ziggler acted like that, from what I know. It was natural and unique. I thought this one was good, though I can't see any fault with anyone calling it forced.
I know exactly how WWE works, and I've already mentioned that they need wrestlers like him. Regardless of his quality, he's merely someone who loses matches to make others looked. He can hold his own in the ring, too. My point, however, isn't that he should be number one - I don't know where you got that from. My point is that he should be utilised better (at his level). Have him in a feud for the Intercontinental title. That's why him being over can help in this situation.
