You may think of him as more of a face, but you are telling me someone like Vickie Guerrero or Randy Orton was a better heel than him?
Orton, I don't consider to be that great at all, and found his heel work very bland with weak promo work and millions of chinlocks. But I will consider Vickie to be one of the greatest of the modern-day villians, merely on the fact, that she took a spot and ran with with it, we watched her awkward start, and seen her become one of the biggest heels this side of kayfabe days. History will be very kind to Vickie Guerrero.
I still never consider Savage to be heelish at all, he was too damn entertaining to be universally booed. He was like Billy Graham in that way, the look, the mannerisms, the promo work are too fan friendly to be effective heel. Did he do some heelish things? Yeah, but let's be honest here, was anyone wanting Warrior to retire him? Did anyone want Hogan to beat him at Mania 5?
