I wonder how many of the current WWE roster actually do their own promo's? HHH and his borefests probably are, HBK, Taker.....who else?
I would think that all the money makers are allowed to say what they want within reason. HHH, Shawn Michaels, Undertaker, the Rock (in his day), Stone Cold Steve Austin (in his day) and Flair are all good on the stick. Guys like John Morrison, The Miz, Mark henry I would imagine are told what to say by WWE creative. From what I have heard and read, Dusty Rhodes is they guy who is backstage at RAW & Smackdown tapings that is teaching the newr guys how to deliver a promo. I noticed for example, since Kofi lost his Jamaican accent and has aquired a more mean streak, look how much better his promos are. That shit he did on Orton's Nascar last week was priceless.
