1. For one....of course the Nwo angle. It was all done on some genius shyt...Hall kicking it off with the opening salvo that led you to believe there was a legit invasion of the WWF coming to WCW to challenge the hierarchy on top. More credence was added when Nash appeared a couple of weeks later....they had Sting eventually slap Hall and give them some backbone. Then the challenge was made for Bash at the Beach with the best set up and heel turn in wrestling history. They back up plan was Sting being the third man and it would of worked but Hogan was perfect..he was from the WWF, the anger fans were developing for him in 95 and 96 had become pronounced, and he cut the promo of his life to match the energy of the moment. You can't tell fans something is great...they have to experience it first hand which is why it got over so well and the trash hit the ring in record time.
2. The transformation of Sting into the crow rebel to the Nwo..of course with the nwo running roughshed over all faces in WCW and backing up everything they were saying in those promos about a hostile takeover and always having the advantage. The angle of if Sting could be trusted got to it's endgame and when it was all said and done, when they were sitting pretty as the Pablo Escobar of the game, he returned and was the perfect foil that the fans would cheer over cool heels the Outsiders everytime. The execution was INGENIUS overall. Setting up the biggest WCW PPV buyrate payoff in history....Sting vs Hogan Starrcade 97.
3. And no matter how much the internet may hate him, may criticize his place in history because of his greed and his ego and him being a mark for his own character, the rise of Goldberg was a very slick and creative push. The thing fans never understood is that he was given a lot...a lot of wins and everyone jobbed but the fans didn't HAVE TO CHEER for him as he kept winning in Tyson like fashion but they did and it created the flash of greatness they needed two years into the Monday Night Wars boom that the Nwo initially brought to the fray. Goldberg was RED fukkING HOT in 1998 but they didn't follow it up the right way the next 3 years and that led to their ending along with the idiocy of Kevin Nash but that's already understood. Goldberg should of been the weapon they had to keep fighting the grip Austin had got by 99 and the stomp of dominance after Rock added his power post Backlash 99. They ended his streak in a silly fashion and never recovered. But the PUSH and how it had everyone asking "who would beat him?" was a difference maker for the timeframe.
