Yes I know about Jonathan Boyd and that he was also one half of the "Kiwi Sheepherders" in the early 80's when Butch Miller returned to Australia but remember I said controversial since Piper. Heck there were plenty of controversial wrestlers like Killer Kowalski, Captain Lou Albano, Larry Zbyszko, Ric Flair and the Horsemen, Buddy Rogers, Gorgeous George, Adrian Street, The Sheik, the list is relatively endless.
Like Piper, Edge knows how to play on peoples' emotions and how to take advantage of an opponent to win a match.
