Name one player who gets paid to go around the country playing exhibition straight-pool on 8 foot tables with 5" corners all year .
Yes, that is the real reason.
There are many players today that shoot straighter and have a better CB than Mosconi had, but they don't play the game every day for hours on easy equipment. I'm sure Willie had greater straight pool knowledge than most of today's players, so his patterns and breaks gave him an advantage, but put guys like SVB, Dechaine, Shaw, Daz, and Orcullo on that same easy equipment and put $100K up for the first one to break the record and I'm sure it would fall in a matter of months.
