See, I disagree to an extent, probably mostly due to nostalgia, ha ha. Sure, Bulldog was carried in his greatest matches, but all but the best are, and he had a number of really good matches that I don't think you can say that he was being carried in. His feud with Curt Hennig was amazing and highly underrated, and even though Curt is one of the greatest ever I don't think you can discount Davey's role in that feud. His first WCW run was pretty good too, he had some good matches there. He even drug The Warlord to a few passable powerhouse matches, probably the only singles matches Warlord had that weren't 100% trash. He could go up until he blew his back out in WCW on that stupid Warrior trap door. For a long time he was probably in the top 5-10 in ring performers WWF/E had.
His biggest issues were outside the ring - steroids, his back injury, which led to drug addiction. If he wasn't a roid hound he had a legitimate shot of being a main event player - he's certainly a case of unreached potential in my mind because of that. His lack of mic skills weren't as big of an issue back then because WWE were more likely to use manager's.
One thing that not many know is how good he was at chirping the crowd at house shows. He wouldn't do it on TV often to stay with the storylines, but I saw him as a heel at a number of shows and he would yap with fans while Owen was in the ring all the time, and it was hilarious. Certainly added a new dimension to the shows at the time.
