Most round prop bettors are looking at the wrong variable.

They're asking: "Who's the better fighter?"

The question that actually makes money is: "Who's the better fighter in rounds 8-12?"

Those are different questions. And the books are pricing the first one.

The Cardio vs Power Matchup Structure

Almost every boxing fight follows the same arc:

• Rounds 1-4: Power fighter is dangerous. His output is high, his punch quality is peak, and cardio hasn't been tested yet.

• Rounds 5-7: The transition zone. This is where the cardio fighter starts taking the fight back as output declines.

• Rounds 8+: If the power fighter hasn't finished it, the cardio fighter is now fighting a visibly slower, lower-output version of his opponent. The late rounds become almost a different fight.

The edge isn't in picking the winner. It's in identifying which rounds are mispriced based on this arc.

A Real Example of the Edge

A -300 power fighter will often be priced as a heavy favorite to win rounds 8, 9, 10. But if you've tracked his last 6 fights, you know his punches per round drops from 52 in round 3 to 31 in round 9. His opponent's work rate stays at 48 across all 12.

Suddenly the -300 guy is a dog in those rounds. The book didn't re-price it because they're pricing the fight outcome, not the physical arc.

That's the edge.
