2nd best stable ... I don't like all these people going for NWO, DX, Evolution, and all those in-your-face loud 90s/ early 00s efforts.
I'm old school for life me. So I'm going to put these names out there:
1.
The Dangerous Alliance: Led by Paul E. Dangerously (with a massive phone), this stable had Rick Rude, Arn Anderson, Bobby Eaton, Steve Austin, and Larry Zybysko. They were extremely hard and extremely cool. They often used to all wear tuxedos and just looked badass. I'd take these guys over Hogan, Hall and Nash
any day of the week.
2.
The Heenan Family: specifically the 1988-90 incarnation. Heenan had Andre the Giant, Mr. Perfect, Ravishing Rick Rude, Haku, The Barbarian AND The Brainbusters (Arn Anderson and Tully Blanchard). And, during that time, he was heavily allied with Ted DiBiase as well. So the greatest manager of all time with one of the WWF's all time legends (Andre), two of it's greatest ever heels (Rick Rude and Mr. Perfect), one of the all-time best tagteams (Arn and Tully),
and Haku -- who was hard as hell -- plus occasional help from DiBiase (see Mega Bucks vs. Mega Powers angle and when he helped Perfect win the IC Title).
NWO?? Pffft. These people had real talent.
Although I will say this: from a smarky perspective making three of the laziest workers with some of the worst attitudes ever heels was an inspired move because someone like me hated them
already. In all honesty though, I think the NWO angle went crap right around the time The Giant came in -- which was pretty soon.
Heenan Family and Dangerous Alliance FTW
