He doesn't do a move called Dream Crusher. It is called Dream Street.
Anyway. Kofi's finisher was the last one that I thought looked good and a devastating finisher. It was innovative and nobody had done it in WWE well not that I can remember anyway. It was a perfect move for his character and fits him perfectly.
Ahem. Not to correct a corrector, but I'm afraid that I'm going to have to burst your bubble by having to refresh your memory on your claim of Kofi's finisher. It was in fat The Cat Ernest Miller who first used it. He only used it once during his short stint as a WWE performer on an addition of Velocity. And while we may all not look fondly on Ernest Miller's in ring skills, he was the master of this move as he performed it expertly from not only in the ring, but also from the top rope. Yeah, I said from the top rope. he would run to the corner and bound up the middle and top ropes, push backward off the top turnbuckle, and then turn in midair to deliver the kick to the face known as The Feliner.
With that said, I would have answer the question at hand by saying it's a tie between two men.. Brock Lesnar and Rob Vam Dam.
When Brock Lesnar debuted, it was the end of a magnificent era where all a wrestler had to do was wrestle while having a manager be his mouthpiece. And Brock did just that. He was strong, fast, big, and athletic. And when he unleashed the F-5 on his opponents, it was the end of the line. And while it's been done by others, Brock did it the best. He used his sheer raw power to make sure that whoever he delivered it to sold it properly. They had no choice in the matter. And that was how it should be with some people.
And now, Rob Van Dam. While man of you nay sayers will point out that The Frog Splash was also done by the late great Eddie Guerrero, the fact is that RVD made it believable. And it wasn't so much that the move had the same devastation of the F-5, it was the fact that RVD sod his own move so well that it made it look like he had just hit his opponent so hard that RVD got hurt in the process. It was like art watching him fly through the air and then hit his opponent flatly and then roll around holding his own chest before pinning his opponent. Shit, he even still sold the move after the 3 count.
Now while some of you will point out other tough looking moves, but when you run down the history and look at footage, you will see at least ten times where those moves were sold badly. When you look at the WWE runs of the two men, you will see that they took matters into their own hands to make their finishers memorable. And that's all I got to say about it.
