at 4.5s ? come on
all the progress in the pro game is irrelevant at the 4.5s, not to mention the 4.0s.
do you have any idea how GOOD this guy's overhead, volley and drop shot will be?
if he parks at the baseline, he wastes all that asset.
let OP decide, if he prefer to park at the baseline, or pick off all those floaters at the net.
we are talking about OP, being a 5.0-5.5 equivalent in badminton! he should play badminton brand of tennis... and you want him to park at the baseline and play pingpong like all the other guys in the videos above?
