Win Methods
Kwon Won Il, better known as "Pretty Boy", brings a 14-6 record into every walk to the cage — and in a division as crowded as bantamweight, every single win matters.
On the feet he's a problem: 5.02 significant strikes a minute at 40% accuracy, and 86% of his wins end in a knockout. The math is bad for anyone standing across from him.
He's coming off a loss to Juan Diaz. Careers aren't defined by the fall, though; they're defined by the rebound.
