Li Jingliang

Li Jingliang, better known as "The Leech", brings a 19-9 record into every walk to the cage — and in a division as crowded as welterweight, every single win matters.

He fights at a pace most of the division can't hold — 4.46 strikes landed a minute, every minute. By round three, opponents are usually fighting his fight.

The last fight went to Carlos Prates (KO/TKO (Punch) R2) — a setback, and the interesting question is always what a fighter does with one.

He's 38 now. Fighters at this stage aren't building toward something; they're spending what's left, and that usually makes for the best fights.
