First of all, KB, saying that Sting has never performed on the biggest stage of them all is just downright false. Sting was the headline name at arguably the biggest PPV in wrestling history. WCW kicked the WWE's ass for nearly 2 years. So, Sting HAS performed on the biggest stage of them all.
I think your last sentence explains everything there is to be said about it really. The only show I watch properly is the WWE, and I never watched WCW. I am therefore maybe slightly ignorant to what Sting has done. All I've seen is things recently, and videos of matches - which I've enjoyed - but can you really use random matches to assess how good someone is as a wrestler?
Up until I started using Wrestlezone, Sting was never a character that popped into my mind. If you didnt watch WCW, he means nothing to you, is basically what I'm trying to say. And with WWE being the company, and Mr. McMahon being the most important man in sports entertainment, I don't think Sting will remembered as well as he should be.
It comes down to many fans of the moment only caring about WWE and their superstars. The old generation of wrestling fans are slowly fading away, and you're left with people who have only been watching the business a few years, who haven't even heard of the Monday Night Wars. Who will hear Sting is in TNA, and will brush him aside. He'll be known as great by many people such as yourself KB, but with how the business has moved on so fast, and with him never being with the biggest company, I think that will limit his legacy.
You make a solid point, although I wish to use it differently.
The biggest problem with Sting's legacy is NOT the fact that he didn't work for the WWE. Rather, it's that wrestling fans today don't have the first damn clue about the workers of yesterday. I mean, let's stop and think for a second. How sad is it that one of the greatest American workers of all time will be nearly forgotten, simply because wrestling fans are too lazy to learn about him? Hell, the same thing is happening to Randy Savage and he DID work in the WWF/E. But, because he isn't shoved down our throats like Ric Flair was, the inclination of wrestling fans today is, as you said, to forget about them. And, I think that speaks more to the quality of wrestling fans today, than it does to the quality of someone of Sting's caliber.
Now, what do I think Sting's legacy should be? Wasted talent. Not wasted by Sting (although, he really hurt himself in '96 and '97), but wasted by the NWA. Sting, and Lex Luger for that matter, SHOULD have been the next Hulk Hogan. They SHOULD have been the NWA's answer to the WWF and Hulkamania. But, instead of pushing these guys to the moon, the NWA was worried more about their bureaucracy and paying dues. I remember being a little kid, and Sting was THE big thing in NWA/WCW. And, just like I did for Hogan, I marked out hardcore. My Sting wrestling figure was the greatest (I wish I still had it too) and I would play with it all the time. But, unlike Hogan, Sting didn't always beat the bad guys. Sting didn't always come out on top. And so, if Sting is not as good as these other guys, and is constantly fighting for the United States title and not the World title, how can he be as good as Hogan?
It was stupidity. Sting's charisma was simply unmatched in the ring. He may not have been as polished as someone like Arn Anderson or Barry Windham, but the man knew how to work, and he knew how to connect with the crowd. And damn it, the NWA/WCW should have put ALL their eggs in Sting's basket, and rode him like a fucking horse. Because Sting had IT. He was fresh, he was energetic, he was athletic, and he just had something special. But, instead of jumping behind Sting, the NWA fucked themselves over. It's for things like that which always make me shake my head at their foolishness.
So, when it is all said and done, I will say THAT is what Sting's legacy will be, in my mind. A guy who SHOULD have been the saving grace for NWA/WCW, but who kept getting pushed down for reasons still unknown.
