It's hard to compare different generations. That's why I now choose to say 'Greatest of the modern era' to clasify Lin Dan. Regarding your comparison of Lin Dan to Yang Yang.... There are a few major differences. 1) Lin Dan was never truly 'schooled' by anybody. Even if he did lose to someone, he would always return the favour with LOADS of interest. His 'track-record-&-performance' againts Taufik & LCW is the main proof of this. Yang Yang on the other hand will always have ZJH whom seem 'superior' in every way except sadly the story we all know. 2) You my say that both Yang Yang & Lin Dan are athlethic,... but the truth is that Lin Dans Athlethicism is at such a different level & pace. Play both players matches together at the same time and Yang Yang desn't look very ahlethic anymore. Fit maybe. Perhaps you should compare Yang Yang to Lee Chong Wei?
