That seems a bit harsh on YYS. I agree with the latter part of that but he is not without any outstanding talents, it's just that its not so obvious. YYS technique is not the prettiest but he does have some strong qualities. His smash is perhaps the most notable. He possesses one of the most accurate smashes in MD in my books and was devastating with the power he could generate. Not many had this combination. The philosophy he adopted when he partnered LYD was not to smash crosscourt very much or risk going for winners - presumably to ensure a better chance of engaging LYD at the front and better win rate. So he was limited on where he could place his smashes. He would aim most of his smashes at that awkward elbow area of his opponents time after time. None of his other team mates were able to do this as consistently - including the late JJS. This was a clever tactic as I'm sure YYS knew he couldn't sustain a hard smash for long unlike KSH or JJS so he had to play a smash that had the highest chance of a weak return to share the load with LYD. He was also very consistent on service returns. Hardly any mistakes despite a rather unorthodox playing style.
