Miz has great mic skills and he plays the heel well. His wrestling skills are barely above amateurish, but he has been improving quite a bit. I'm not going to say I'm a huge fan, but he is not even close to the worst on the roster, let alone RAW's roster.
Ultimate Warrior sucked and always sucked, he was a flash in the pan. Macho Man on the other hand, now that was a wrestler.
Well if you consider saying "I'm Awesome" (aweful) a million times great.. well then so be it..
