For me , I tend to agree with LCW that Lin Dan should retire now or maybe even earlier, perhaps just after the Rio'16 Olympics. However, with the benefit of hindsight, I'd much prefer he retired just after winning the Asian Games MS title in 2014 (beating LCW in the semis and Chen Long in the final) and then injured his knee while playing friendly soccer with his buddies, which he claimed was the worst injury he ever sustained in his career. Ideally, it's good to bow out on a high but I'm suddenly reminded that he had signed a lucrative multi-million dollar 10-year contract with Yonex (2015 through 2025), so I supposed he had no choice but to carry on active competition initially for a number of years before finally hanging up his racquet for good (probably after the Tokyo 2020 OG if he qualifies, the more so if he didn't). That's just my opinion. Well, we can speculate a bit on what Lin Dan might be doing post-retirement and I'm pretty sure he'd do his utmost to stay relevant in the badminton world, not as an active player but as promoter and popularizer of badminton globally. To be honest, I much hope he finds some time to coach CHN WS since Li Mao is already in-charge of CHN MS and will be for quite a while.
