Errol Spence Jr.

Nobody hands you anything at welterweight. Errol Spence Jr. — "The Truth" to fight fans — has built a 28-1 record the hard way, one fight at a time since leaving the United States's regional scene.

The style is simple and terrifying: 79% of his wins never reach the scorecards. When he touches people, they fall — 22 knockouts and counting. Add the southpaw stance, and the puzzle gets harder still.

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

At 36, the window is what it is — which tends to make every remaining fight more honest, and more dangerous.
