I've seen him play in Korean leagues quite recently. Still a work-horse with no decisive impact on court, but too inefficient to be a solid base for someone else to play off of. His technique is weird as well, imop.
Maybe Top10 potential with just the right partner, but tbh he'd be holding that guy back. In some aspects he's a bit similar to JJS, but in everything that made JJS great, he's average at best: deception from the back, easy power, great shot selection, very solid defense - all things I'm missing when looking at this guy.
Anyway, I think Ko and Shin are Korea's best shot at a medal (mb outside of WD, they seem to be getting back to where they once were), and they're most definitely a better selection than a pair that's never won anything significant and isn't making any progress or showing potential.
BTW, that win was definitely a fluke, nothing yet to be seen. It's been years and nothing noteworthy. If CSG ever does anything of importance again, it will be entirely unconnected and the SC win would still be a fluke. Not quite as surprising as the Ellis/Langridge taking home any metal other than scrap, but almost up there.
