Part of professional wrestling is grooming talents for the future. The success of a group isnt just measured in the stars that it currently has, but also the stars that it makes. The nWo was littered with stars who were already made, and were therefore past their primes. It could be argued that the biggest stars made in the nWo were Scott Steiner, Buff Bagwell, and Konnan. Before Triple H was Triple H, he was Hunter Hearst Helmsley. DX made him Triple H, and for all the grief Hunter gets for marrying the bosss daughter to stay at the top, it was DX which brought him to the top. DX also made household names out of Chyna, X-Pac and the New Age Outlaws. Theres no way the Outlaws would be in any position to win a tag team championship 14 years after their previous title win if not for their inclusion in DX.
