Well, only if you are opposed to facts. Facts don't lie.
1. As a species, our hand eye coordination is no better than the 60's, or anytime previous. (No athlete has ever surpassed Babe Ruth's hand eye coordination imo).
2. Our brains are no more skilled today than the 60's. (Einstein is still holding his own, as is Galileo, DaVinci, and Socrates).
3. These are the only 2 points that can be argued in regards to players of the past. Everything else is semantics. Period, end of story.
Your scenario says players of the past couldn't get there today, yet everything you base your opinion on, is simply some form of acquired knowledge, not skill. Your opinion also says players of the past, don't posses the mental faculties, to acquire knowledge or learn new things. (Wonder how they learned in the first place. My opinion is based on physical skill, which is what we are arguing about. You and all your ilk, argue knowledge, then deflect and call it skill
So are today's players more knowledgeable, yes, skilled, show me how.
Lassiter, Buddy, Etc...had it, end of story. They rose as high as was possible during THEIR time, with what was available, at the time. Were they alive today, they would do it again. They are the .0001% of the world, that would stand at the top, no matter what time, age or conditions.
