Probably nowhere, I think everyone thinks that. But then why did so many other big stars end up joining it? It got way too big for it's own good, it should have been kept small, then it would have been a straight up equal to the WCW roster.
Hogan working against nwo would have been ok but the storyline would not been great. Nwo always get credit but Sting should also
If Hogan had been working against the nwo, the angle would've died (perhaps due to Hogan's politics), they would've probably been in the same boat as the dungeon of doom and 4 horseman - where they team up and still lose to Hogan and Savage like they did in that weird steel cage match (can't remember the name of the PPV).
