Evolution was a blueprint of the four horseman. If you look at something in a small scope you will see what you want. In this instance you could say ANY faction with an established wrestler as leaderhead is a rip off of the horsemen. I think every group used this blueprint:-
DX was essentially the same; Rick Rude (Legend + enforcer), HBK (established star), HHH (rising star).
Second reincarnation:-Triple H (leader + now established), Chyna (enforcer figure to some extent) , X-Pac, and the New Age Outlaws (Road Dogg and Billy Gunn)
The only similiarity i see in the "new" nexus is there's a leader (CM Punk) and a guy who looks like batista.
There's no "legend" taking the youth under his wing, there's just 3 rookies that aren't exactly being groomed for a world title win. Evolution EVERY member was destined for success. Nexus, only two (ryan and punk) will benefit imo.
I do see minute similarities between New nexus and evolution but there are more striking similarities between Evolution and the Four Horsemen (The layout, the suits, party animal attitudes etc) which just goes to show that most things in wrestling are recycled.
