Yes. I too did the same, and I was older...a cocky teenager. No old timer could touch our generation(I was a BIG hitter), don't even try your silly eastern backhand against my semi-western! It was....well several lines of education that opened my eyes. Not the least of which was having the chance to hit with PRO players of previous generations. NOT GREATS mind you, just journeymen/women...now I was no pro...but I hit with pro pace (pros and coaches like Vic Braden have told me this, and I knew it was true, arrogant as it may sound)....funny....I couldn't knock those former pros off the court...in fact, with their smooth strokes, perfect timing, and ability to use my pace against me, it was me, if anything who was getting overpowered, or at best, generally neutralized! They didn't say "wow, I never saw that kind of power!!" they said, "hey, you hit with good pace kid (too bad for you, it's nothing I haven't seen before, and I can use it against you...and also, I can hit plenty hard myself if I want!)." Later, as my eye for tennis, coaching knowledge etc. grew more refined, as my experiences on court grew more varied, I began to see the old footage in new light!" I realized that while they weren't leaping off the ground, swinging with all their might, these guys were hitting SOLID, HEAVY balls, with great balance, great footwork, and great control. Their heavy racquets were giving them pace and weight. I realized that MANY of them, at any moment they really wanted to, could generate every bit the pace of a player from any era! In fact, it was the smooth, clean strokes that made it deceptively easy for them to do so. I realized that human athletic norms haven't changed that much. That while the general level of athleticism has gone up, the top guys of any era were athletic prime beef, and would be so in any era. I began to see just how difficult it would be to play these guys, and just how effective their style is. I realized how foolish and ignorant my youthful arrogance had been.
