I'd heard about him earlier this year, but I thought he probably wasn't interested. I think with this, he's locked into playing for Korea. The women's team had Casey Phair join them a year or two ago as well, I imagine she was the first from men or women.
Interesting to see Jeong Sang-bin return. He hasn't really lived up to the potential he seemed to have since leaving Korea. He might not actually get any play time, though.
