Interesting post. I knew both players quite well, gambling with and against Jack Cooney and backing Parica in tournaments and watching him play so many times. First the latter, Jose Parica was the dominant rotation player of his era without question. ALL deferred to him in 9-Ball or Ten Ball. After he crushed Earl at Ten Ball, no one ever tried playing Jose even at either game. Buddy conveniently avoided him. Jose was to put it simply a better player than all the rest of the game's greats at that time. Not Sigel, not Varner, not Archer, not anybody was a match for him. Jose shot straighter, never missing a ball for hours on end and his cue ball control was something to marvel at. I could just sit and watch him roll that cue ball all day long. Yes, better even than the great Efren!
As for Jack he was the greatest money player the game had ever seen, and it was not even close. That he was a stone cold hustler, there is no doubt. But the fact that he was so successful at it set him apart. When all the other top hustlers were looking for four figure scores, Jack was making high five figure and six figure wins, and doing it a few times every year. Underneath all his hustling was a great pool player, perhaps the second best One Pocket player after Ronnie Allen. Jack was way too smart to match up with the other big guns of One Pocket like Shorty, Taylor, Bugs and Ervolino. It would only kill his action and he knew it. He did play one $100,000 set with James Walden at DCC some years back. That was Jack's swan song in pool and he went out on top.
I saw Jack's real speed when he had to show it, and he could come with any shot under pressure. His 9-Ball game was also top speed and he hid that fact well. A few very good players found out that it was not a good idea to challenge Jack at 9-Ball for big money.
