Different eras applies to many sports. I am not so sure it does with pool.
The table is still nine feet and plays pretty similar. Cloth and cushions are better. Cues, too. But great players would adjust quickly.
Just look at how quickly the best players adjusted to tighter Matchroom pockets.
Give guys like Sigel, Varner, Hall, heck even Mosconi, six months to practice and they would adjust quickly to tighter pockets, faster cloth and bouncier rails.
Good strokes, good techniques, good pattern play are timeless. Better cues and other equipment only help.
Let them watch new players and they’d pick up all the new tactics and strategies, too.
Would they win as much now? No. The biggest difference now is the sheer number of great players vs. the past.
The old players, transported in time, would need personal trainers, too. The pro pool game is as grueling as ever. Smoking, overeating and being out of shape would be bigger detriments.
