People seem to forget that O'Sullivan has chanced his arm at 8 ball pool and came up rather short:
He was "in" those matches though. Getting 6 games in a race to 8 against Bustamente when Busty was in his prime, getting 7 games in a race to 8 against circa 2006 Corey Deuel is significant. Beating Karl Boyes, who at that time WAS already an accomplished pool player.
He went into the IPT as a laugh, he put in not a whole lot of practice or effort, and he did not embarrass himself, he was actually IN the matches. Of ALL of the people in the IPT Ronnie was likely the one guy that did not give two shits about the so called "massive" money that the other pros practiced like crazy to try and win. 1st place in the IPT was gigantic to "pool" players and they practiced like crazy for those events. For Ronnie the IPT was "not" a step up in the money he was used to competing for, it was a step down.
There have been many snooker players who have went into the World 9-ball Championships and who have been very competitive match for match. They have won matches against pro pool players and have gone deep in world pool championships. There has NEVER been a single "pool" player who has won a SINGLE match in the World Snooker Championships, there has never been a "pool" player who has ever even managed to get there.
The distance that a pool player is from pro level snooker is WAY greater then the distance a pro snooker player is from pro level pool. And I am talking a HUGE distance. One would be swimming downstream, the other would be like trying to swim up a freaking waterfall for most pool players.
