Andrei Arlovski

Andrei Arlovski, better known as "The Pitbull", brings a 34-24 record into every walk to the cage — and in a division as crowded as heavyweight, every single win matters.

The record shows a bit of everything: knockouts (17), submissions (3), decisions (14). Well-rounded is an overused word; here it's just accurate. Add a 77" reach, and the puzzle gets harder still.

The last fight went to Martin Buday (Decision - Split) — a setback, and the interesting question is always what a fighter does with one.

He's 47 now. Fighters at this stage aren't building toward something; they're spending what's left, and that usually makes for the best fights.
