Mick Parkin

Mick Parkin holds the #15 spot at heavyweight, flying the flag for England — and rankings that high aren't given away, they're taken.

On the feet he's a problem: 4.7 significant strikes a minute at 54% accuracy, and 60% of his wins end in a knockout. The math is bad for anyone standing across from him. Add a 79" reach, and the puzzle gets harder still.

He's coming off a loss to Marcin Tybura. Careers aren't defined by the fall, though; they're defined by the rebound.
