Come to think of it, you are absolutely right. Incredible and unprecedented, I supposed. Chen Long at Rio'16 blew me away, so masterful - his attack neat, crisp and powerful, defence tenacious and amazing, counterattack (turning defence into attack) brilliant, most of all, he was able to maintain a high consistency and quality shotmaking round after round to sweep all before him. Sadly, since then, esp after his six months break of his own initiative (and resting on his laurels), he was never the same again.
