The poll is peculiar in that "none of the above" is not even a choice.
My days as a regular on the pool scene go back to 1976. I don't feel any of these would look out of place in the BCA HOF, but that said, I don't think any of them belong -- the title count just isn't there.
I'll add that the first few US Open 9-ball event had tiny fields, as small as 16. and all occurred before the competitive landscape became truly global. Yes, it grew into a big field event with an elite international field by about 2000, and is now the sole domain of the superelite, with the last five won by Sanchez-Ruiz, Biado, Filler, Shaw and SVB.
These points aside, if any of these fine players are elected, I'll be happy to congratulate them at the induction ceremony if I'm lucky enough to attend.
No doubt, there's a fine line between being great and being hall-of-fame-worthy.
