I was a fan of his wrestling before his injury on that piledriver from Owen. His wrestling skills were very good and I used to enjoy watching his matches pre-injury, especially when he was in WCW.
I did like the Stunner, it was an impact finisher that you knew the match was over when it was hit. Not the main reason I like him though. I really liked his bad@ss character, like others have said he was blue collar and went out and got what he wanted even if he was tried to be held back.
The most that I liked him for was his character, especially after his injury since he couldn't wrestle much anymore like he used to. He had a lot of charisma and just knew how to entertain the fans, had great mic skills. I know a few users have said he had a lot of his promo stuff written for him....but there were times he adlibbed while on the mic, that takes skill. Plus, his original King of the Ring victory speech wasn't written for him..and that got 2 catchphrases started: Austin 3:16 says I just whipped your @ss, and That's the bottomline, cause Stonecold said so.
