I say that because Mike Massy comes to mind. He does things that look like a camera trick and does it on demand. There used to be tape out of a guy doing amazing trick shots. As you watched the tape you can actually see the ware and tear on the table progress. He must have shot some of the shots hundreds of times to get it on tape. The table goes from looking like new to beat to hell in the course of the tape.
I am not being picky but when a guy can steps up and say, "watch this" and does it, that is impressive. I remember Jimmy Caras, he did mostly set up shots but also a lot of skill shots and he almost never missed. Mosconi would miss like half his exhibition shots and he just had jokes he did if he missed. Caras was very dedicated to his show, he always got it right.
I remember at the US Open straight pool tournament once there was a delay for some reason and Cue Ball Kelly saw Caras sitting there and said, " Jimmy you want to fill a few minutes? He stepped up to the table with a borrowed cue and did like 15 minutes, never missed a shot. He was really great. I guess I am a little hard on these guys today who do shots on youtube with unlimited time to get the shots on tape. Not quite as impressive.
