Speaking clearly or intelligently doesn't make a promo good. That's just one style. The important part is how hyped it gets the audience, how much they want to see you MORE after watching the promo. For a heel, it's how much the audience wants to watch you get your ass kicked based on the promo.
Piper was a master at promos because he knew how to connect with the audience, draw them in, and make them want to see his next match.
