I think WCW never putting the stake in the heart of the nWo helped lead to its downfall in a major way. The good guys never won, so why cheer for them?
That said...
*****
Sting beats Hogan clean at Starrcade. Hogan gets some offense in, but in ten solid minutes, Sting cleanly wins. No interference.
Hogan gets his rematch at Souled Out, and all signs point to the NWO interfering, but the WCW faithful fight them off during the match. Sting hits the Stinger Splash, but Nash pulls him off and starts wailing on him. Hogan grabs a chair, goes to waffle Sting, but misses and cracks Nash, Sting hits the Death Drop and gets the win. Bret Hart beats Randy Savage on the undercard.
Now Nash and Hogan start pointing fingers, and you can sense the tide is turned firmly in WCW’s favor. During the lead up to Superbrawl, Hogan says he’s going to make things right and make sure the Outsiders keep the tag team titles against the Horseman team of Chris Benoit and Jeff Jarrett. At Superbrawl, in a competitive match, the Horsemen take the gold because Nash spent most of the time staring at Hogan to make sure he didn’t do anything, but Hogan never interferes, so the loss is “all on Nash.” Also, in a #1 contenders match, the Giant beats Randy Savage to become the #1 contender.
Nash and Hogan go at it at Uncensored, with the winner taking control of the nWo, and Nash wins. Sting beats the Giant in the main event. Ric Flair beats DDP in a tough match to become the #1 contender. Goldberg starts (or continues) his streak here against Buff Bagwell. Bret Hart and Dean Malenko go to a draw over the US title during this as well in a well-book, well-received match.
Now, we get the big lead up to Spring Stampede, Ric Flair vs. Sting, and Nash plans to stick his nose in. Flair and Sting unite during the weeks leading up to it to fend off the NWO, along with Bret Hart providing back up and drawing the ire of one Scott Hall, who pledges to put Hart out for good. On the Nitro before Spring Stampede, however, Flair and Sting are in the ring, brawling with Hogan and Nash...and as WCW stands triumphant for a moment, Flair hits Sting from behind, before nodding to a confused Nash and Hogan and leaving with the rest of the Horsemen up the aisleway, causing the announcers to wonder what the hell happened until someone says “Did the Horseman just side with the NWO?”
At Spring Stampede, Bret Hart beats Hall, and pledges to cut the heart out of the NWO by defeating Hogan once and for all. Benoit and Jarrett come out in black-and-white outfits for their match against Lugar and DDP. Goldberg defeats Chris Jericho and becomes the #1 contender to Dean Malenko’s US title. Flair comes out in a black-and-white robe and goes all out old-school heel against Sting, but it takes Hogan and Nash interfering for Sting to lose and Flair to become World Champion again.
The next night, everyone in the NWO is talking about how the Horsemen are with them. At the end of Nitro, Flair’s in the ring, being booed hardcore, until the NWO come out, and Hogan makes an official offer...and Flair cuts a classic promo about how the dirtiest player in the game took full advantage of the NWO's gang tactics and let them beat Sting bloody so he could win the title back. “I don’t need the NWO! You’re nothing anymore! Your moment in the sun is done, baby, and it’s time for the Horsemen, whoooooooooooooooooooooooooooooooooo, to ride again!” Cue a NWO/Horsemen brawl that ends with Sting repelling from the ceiling and beating up both sides with a bat.
The rest of the summer is Horsemen/Sting and his allies Lugar and Hart/NWO fighting for supremacy. Goldberg takes the US title from Malenko at a Clash of the Champions and starts a solid run with the belt, remaining undefeated over the summer.
This all leads up to Fall Brawl, and War Games.
It’s a three-way War Games, with Benoit/Jarrett/McMichael/Flair on one side, Hogan/Nash/Hall/Henning on another side, and Sting/Luger/Hart/DDP on the last side. Losing team disbands/can never team up again. Goldberg beats Savage in 5 minutes on the undercard to retain the US title. Luger gets jumped by the NWO and taken out (due to a real life injury he suffered during the week), so WCW is down a man. But they soldier on, and the last man in the cage is WCW’s...
...Goldberg.
He wrecks the joint, knocking Henning clear into another cage with a clothesline, before grabbing Nash...and Flair waffles him with a steel chair from behind, which does nothing. Flair pleads, but Goldberg spears him and takes him out. DDP Diamond Cutter’s Nash, Hart locks Hall in the Sharpshooter, and Sting Death Drops Hogan one last time before locking in the Scorpion Deathlock and making Hogan give up.
No more NWO, and it’s WCW with the win, and not the NWO turning on themselves.
I think eventually, Sting/Goldberg is the dream, but at the same time, you need Flair to help build the angle. Sting’s good, but Flair made him magic, and I think he could do the same for Goldberg. And now you can legit add Hart to the mix. And Nash and Hall are still around, and Savage, and Hogan, but they're not RUNNING things anymore.
