Agreed. Has some great titles and he's a legend of the game, but he hasn't prevailed over the game's most difficult internationally balanced fields and it's a significant hole in his career resume.
Anyone who thinks that the US Open fields of the last twenty years are, on average, as tough as the World Championships fields is just plain uninformed.
If you look as the game's biggest ever paydays, Efren won the All Japan Championships when the first prize was about $180,000 and he won two of the huge purse IPT events including the one that carried a first prize of $500,000. And yes, Efren has won a World 9-ball championship. In the very biggest spots, SVB's record pales compared to Efren's.
