Shane didn't gas, thats absolute foolishness.

Mayweather made the necessary adjustments and with his lightning counters, totally limited Shane's output just like he does to all his opponents. Instead of standing upright like he did when he got caught, he was stepping back and countering. Shane knew this.

Why is it so hard for some to believe that its not as easy as just standing in front of a guy like Floyd and throwing hands? Floyd flustered him and muscled him, end of story.

Mosley gassed after 2 rounds? If you believe that then I don't know what to say to ya.
