Hogan killing wcw is straight internet mark talk. Dirt sheets cried about him for 20 years playing politics and then every champ after him did the same exact thing if not worse and didnt say a thing about it.
Wcw was only a player because of hogan. Period. No hogan, no nwo, no nitro, no rodman, no big time appearances on leno and with malone. Etc None of that happens without hulk coming in.
Wcw died because wrestlers need a strong leader who makes decisions. When you have a revolving door of leaders, you just bide your time until the next one comes in. Only the owner (turner) himself coulr have gotten that place in line.
Hulk built and destroyed.
The business of wrestling survives by a character being built up and then creating new stars while on top. Andre put Hulk over and after that Hogan stayed on top and most of the time weasled his way out of doing business properly. He put over Warrior only because he was getting stale and wanted to go make movies, but then made WCW sign warrior just so the petty bytch could get his win back(and cost wcw more money).
Fact is, not putting Sting over clean was a big reason why WCW never survived.
