Just the opposite.I don't think he does.
The skill required to manhandle an opponent in a rotation tourney is far less than that required to run 14.1 like he does.
pont being, lots of guys can run 9b racks but not a lot can run 200+...and even fewer can go 500+.
In the straight pool era, champions regularly defended their titles, because it's a game that, at the highest level of competition, enabled them to put opponents in the chair for forty-five minutes at a time on a fairly regular basis. More than a few had the skills to do just that, and some who were counted among the best at straight pool were extremely successful in transition to nine-ball (Sigel, Varner, Rempe) while other legends of straight pool were not as successful (West, Martin, Mizerak, Lane).
There are definitely more bumps in the road to negotiate in nine-ball than there ever were in straight pool, which is why even the most skilled players rarely ever defend a title. Sustained excellence in nine ball competition has always been harder to come by than it was in the straight pool era, and for the most part, no nine-baller has ever come close to dominating the play in the manner that Mosconi or Greenleaf did at straight pool.
