Watching the 80's All Japan set really opened my eyes to Terry Funk as a babyface in the early 80's. He was SO sympathetic, crowd adored him, and he could light up the comeback torch with wild punches, emote facially and audibly with the best of them, bump like an ace, and when he would blade his ear, shit was ON.
As far as dudes that could truly do anything at a high level, Terry Funk and Eddie Guerrero are the primary two that come to mind. Both could brawl, work the mat, work heel, work face, bleed, sell, bump, work varied styles and varied opponents, etc.
What about Lawler? The Bockwinkel matches, Funk matches, Dundee matches, Jimmy Hart matches, Miz matches, etc show his range. He's equally as good face and heel, so on...
I thought people stopped believing in the Angle gaga years ago...
