Try 10 power punches. And 31 jabs, supposedly. But seriously, go back and watch the fight. See if you can see 41 punches (not 42) landed by Gatti. I sure as hell can't.
Mayweather's style is different than Hopkins'. Hopkins circles more and flicks out that jab. Mayweather stays in the pocket with those guys. A lot of those supposedly landed shots are landing on his arms and gloves.
