Since Matchroom changed the break rule circa August 2022, Shane has come up empty at the 9ball majors. 9ball has done a great job of sorting out who the truly elite are in our sport. That's likely to continue.
As we saw at the World 8-ball, 8ball on the big tables is boring to watch and its, basically, a breaking contest for the most elite players, as the run outs are so easy by world class standards. Shane probably has the best 8ball break in the world, and he rode it to victory. It was reminiscent of the days when Shane dominated with his 9ball break, but today's version of 9ball (tight pockets, tough breaking rules) require a far more balance skill set than that needed ten years ago.
Shane wants to return to a world in which his break will give him a gigantic edge over his opponents. Can't say I blame him, but it's big table 8ball that's too easy. 8ball, however, an interesting game on a bar box.
