He was a fun player to watch in his best years, but his style is so taxing to his body that if I were him, I'd be worried about being able to just walk and tie my shoes when I'm 40 than about making it back on tour. Would be good for the sport if he makes a comeback among the best, but it would take a miracle.
Wow I am quite surprised that some fans outside South Korea are curious about him. It seems no one here doesn't even care about him, which is sad actually. Even some people made sarcastic comments that he should get a second life.
I think he won't come back with strong performance maybe top 50 at best, even if he makes a comeback.
It's sad the way that Chung seems to have just become the butt of the joke these days. He was, by all accounts, a nice guy, and an incredibly talented/promising young player before his battle with injuries. Here's hoping he's able to string together a comeback.
