Seokhyeon Ko

"The Korean Tyson". That's what they call Seokhyeon Ko, and is part of the UFC welterweight division's deep end, fighting out of South Korea — 16 pro fights in, still swinging for a number next to his name.

The game is built on grappling: 4 takedowns per 15 minutes, and opponents spend rounds defending instead of fighting. Once it hits the mat, the fight tends to stay there. Add the southpaw stance, and the puzzle gets harder still.

He's coming off a loss to Jean-Paul Lebosnoyani. Careers aren't defined by the fall, though; they're defined by the rebound.
