Sting will never be an icon. Sting was an legend in WCW/NWA/TNA, but that is as far as it will ever go. When people think icon, they think large, big, lots of money, fame, fortune, success, big matches...but most of all, they think WWE.
For instance, the Rock is an icon, but the Rock never wrestled for WCW/NWA. Why is he still an icon? Because he DID wrestle in WWE. Sting is a legend. He will always be a legend, but Sting's legacy will be left in TNA, as a failed attempt to save save the sinking ship that is TNA.
He could have worked so many programs in WWE. So many storylines and angles and characters. He didn't, he chose his morale highroad, and you know what? That's okay, because he did what was in his heart, and he never "sold out". I'm sure he's fine with that. Sting is one of the legit good guys, and stood up for what he believed in.
I hate TNA with a passion, so the fact Sting is there, irritates me to death. I mean, I grew up on watching Sting in NWA/WCW and he had tons of great programs: vs Flair, taking on The Horsemen 1 by 1, teaming with The Road Warriors vs The Russians, Teaming with The Bulldog, becoming a Horseman, vs The Great Muta (my favorite), vs Cactus Jack, Lord Steven Regal, Vader, etc. I went to so many Starrcades and Clash of the Champions JUST to see Sting.
I've always cheered for and admired Sting. I don't watch TNA, even Sting can't change that. I gave it a chance, I watched, purchased ppv's went to a few shows, but nope. Didn't work. I hate their product (not their wrestlers). I hated it when they tried to force that stupid 6-sided ring down our throat, or those stupid ropes above the ring. I hate the fact they repeated the SAME mistakes that ruined WCW by bringing in Hogan, Bischoff, Russo and gave them the power.
As much as I hate TNA and the fact Sting works for them, I respect his decision to not make the jump. Why? Because he did something very important by honoring his word, he did what he needed to do to be Sting: He remained true to himself, his morals and his word. If he had jumped ship, I would have been ELATED to see him in WWE and watch his stuff, follow his angles, etc...but I wouldn't have respected him 1/2 as much as I do now. So no, he's not an icon. At least not to me...a 30 year wrestling viewer, he's something more important than just being an "Icon", he's a Real Man that honors his word because it's what he feels is right. Kudos Stinger!!! I'm proud of ya!
Anyway...that's my two cents.
