Nah fam, letting someone beat you isn't automatically putting someone over. AJ Styles, arguably the best in ring worker in the world, shouldn't have needed twenty minutes and a ref bump to beat a nearly fifty year old part timer who was never a real wrestler. Same with Owens. You don't have a vicious, cunning heel like Owens take forty minutes and outside assistance from Sami to beat that same stuntman. It made both of them look like jokes, that Shane took them to the limit.
The only guy you can really argue that Shane put over was Test back in the day, because Test overcame Shane and the Mean Street Posse. Not that a near seven footer like Test should have much kayfabe trouble beating his bosses son and three preppy rich assholes in a street fight, but hey its a McMahon story. Even then they screwed it up by having Shane become his best friend after that.
