re: Well, the super kick has gone the way of the DDT.

Things evolve. Back in the 80's, finishing moves were simple but protected. You wouldn't see anyone else do a kneelift except for Mr. Wrestling II. Both JYD and Dr. Death Steve Williams both used power slams to finish off opponents (of course, they were called "the thump" and "the Oklahoma Stampede" to differentiate from a "regular" power slam).
