I know this is an old thread but I think its still relevant. Weldon Rogers is spending alot of time near Eloy, Casa Grand Arisona. He is spending alot of time with his long time friend Bakersfield Bobby Hernandez.
I think when they talk about the "The Best Players" it really should be more specific to a time such as decades (50's, 60's, 70's, 80's etc.) And then be specific to the game, including table size, cue ball size, style such as one/two handed, ambidextrous etc. And then venues such as road players vs tournament players. I'm sure you could come up with other issues that might impact someone's play that might make them stand out as the best in a specific or narrow set of guidelines.
It is very possible, in fact very likely to be multiple right answers (players) taking into considerations all the variables I mention above. There is one more consideration; and that is one's personal opinion that can be influenced by how they know a player and who they seen them play and how often for example did players match up on three different occasions and one player won all three times etc.
Okay so finally, I'd like to throw my pick in the hat > in the 60's and early 70's one handed either hand, big cue or standard cue on a bar box goes to Bakersfield Bobby Hernandez. I've played a lot of pool with Bobby and seen him do amazing things, ESPECIALLY with big whitey, he could play the big cue ball like it didn't matter.
Right now Bobby is very ill near his home in Eloy Arizona and he can sure use your prayers
