It is not possible for Bao Yixin to do without Liu Cheng and vice versa ? In life or in badminton ? You mixed up their emotional relationship with their badminton. C'mon , nobody is indispensable, ultimately. That they were not chosen for the Rio Olympics was because they were overtaken last minute by the better performance of Xu Chen/Ma Jin in the world rankings and only two pairs maximum get to go, the new OG qualification rules, remember ? On what grounds do you claim that Bao Yixin was victimized twice, in XD and WD ? What about Wang Shixian, why didn't you say so ? If, as you say, Bao YX without Liu Cheng or vice versa, they simply cannot perform well because they are seeing each other, not for any other reasons related to badminton - that I find hard to accept or understand. Are you implying, every XD pair where the two players are a couple in real life must not be separated, or their game will suffer ? Well, that's a new theory to me, perhaps coaches from now on have to take it into account when they pair up XD players. But, frankly, I don't buy it though I accept that any two players who can't get along in real life will somehow let it affect their badminton partnerships, quite difficult to avoid it, and that not only in XD but also MD and WD; still, not quite the same as what you're driving at.
