Agreed to a point, except the defensive elements, the multirail, and the multipurpose shots forced players to obtain more theoretical knowledge and a little more speed control than their counterparts of a generation ago. Dan DiLiberto often notes that there are countless more good players today than in his prime, and Buddy Hall has said the same. I believe part of the reason is the switch to Texas Express, which forced players to get a more comprehensive grasp of the theory pertaining to cuesports than the players of yesteryear and also forced them to become highly proficient at masses and jump shots.
I would also argue that Texas Express reuslted in a much higher number of good pattern players in nine ball. Today, if you blow the position and hook yourself, the penalty is severe, and you usually become a big underdog to win the rack. It's a much more severe penality than back in the day when you could push out and remain on relatively even footing in your quest to win the rack. Because getting the patterns wrong today is so costly, players spend more time and effort developing their patterns than those of yesteryear, just another reason that there are so mnay good players today relative to way back when.
In fact, when the legends tournament was put out in the early 1980's, you could see just how uncomfortable guys like Lassiter and Crane, still solid players, were when they had to kick in nine ball. It wasn't just their age (let's not forget that Crane could still run 150 and out even then). I know some elderly men today that kick extremely well.
In truth, in today's men's pro pool, a snooker very rarely leads to ball it hand, instead making it difficult for opponents not to leave you at least something, and when pros play safe, they do it to improve, not to perfect their position. Hence, I reject the suggestion that pros play safeties for the purpose of obtaining ball in hand,(though they understand it as a possible, but usually unlikely, upside). Jast as in the distant past, most ball in hand situations are the result of the cue ball finding a pocket.
One may prefer whatever brand of nine ball they choose to play or watch, but because it forced players to develop skills that the players of yesteryear were less dependent on, the game has more variety and the players more skillful.
