You're being very disrespectful to Sting. Look at the man accomplishments in WCW and Especially TNA. He's held total of 21 championships in his professional wrestling career. Sting's tied as four time Most popular wrestler of the year with John Cena.

Sting has the greatest Gimmick all time in WCW History. He's also one of the greatest Professional wrestlers all time. Nobody knows how to learned to give some Legends that, They really deserve. He's giving the fans lot of amazing matches with Ric Flair, Vader and more. We appreciated The Franchise of WCW, The Icon and Vigilante.

Sting is credible in Pro Wrestling. Period.

I'm going to say it, it wasn't the best match at wrestlemania, but it was overbooked, anyways, sting looked like he was in good shape, but I really am not expecting a lot from sting in wwe.

Why is WWE credible in itself?

because he is a veteran wrestling legend

because of his accomplishments in WCW.
