I might have misunderstood, but I don't think the great shoot makers are dead, I just think it depends on the equipment you catch these guys on. Corey came to Houston and played on a table that everyone stayed away from and ran out like water. It was a table setup for One Pocket, like the tables used to be at Hollywood Billiards in LA, he played 9 ball on that table and never missed.
I think there are more shot makers are still as plentiful, Check out Shane vs Rafael on YouTube!
