I believe what proves the point I mentioned is Djokovic, Nadal, Murray, and Fed have elite defensive skills, return of serves, footwork., court positioning, and speed.
Otherwise you are implying that if we give their 2hbh to any 1hbh player that player will instantly have a better win/loss percentage or go deeper in slams.
This will never be proven or happen in the pros.
Have you seen it work at the rec. level and if you did witness it, did you omit or include other improvements to their game during the transition such as training, shot selection, court positioning etc.?
A controlled study similar to drug efficacy and various groups is the only true way to prove the point.
My condolences for Tsitsipas' 1hbh beating Etcheverry, Zverev, Khachanov, Sinner and a 2hbh clay ct specialist, Ruud, in one week.
Haha, okay, yeah I know. You could provide endless accounts of Djokovic, Murray or Nadal and the OHBH players they defeated, incl. Tsits, Thiem, Dimi.
It's all good, just having fun. If only every 2hbh player could be like Djokovic and able to hit slice like a OHBH plyr. The next generation will probably mimic him and give us another advanced tactic. Scary.
