The finisher is the "actual" John Hancock of a wrestler. They start the match, fighting and batteling to the "high point" and then the finisher comes into play. Deffinatley is a key role in making somebody's carrear or breaking it.
There are plenty of superstars of there that have some pretty good finishers and aren't that big a deal, ie. Evan bourne, but he is over with the "target" audience. Someone mentioned previousley about HBK and the belly to back suplex, and that is one of the best examples I could have thought of.
If HBK had stck with that as a finisher IMO he would have has 2 have a couple more signatures or "big spots" to have been so "over" as a character. Idk but some how the super kick is just HBK, that's who I associate with the move because IMO he does is best. It made him, I mean, "tunin up the band for a little sweet chin music!" It gave hime more depth, like stats if you will for pro sports, wrestlers had "special" moves or knock out blows, its all there.
However there are some exceptions to the rule when it comes to that, because some of the TOP guys in hisory have had BAD finishers. For god sake all Hogan was doing was a glorified leg drop, but it in some way was a MAJOR deal when he did it. Like with The Rock"s peoples elbow, DUM ASS MOVE, he just made it work and IMO because he's the rock it worked. So it kind of is a double edged sword I guess..
