What could Shane have done to finish off Floyd in the 2nd Round?

Indeed it was a death grip on that arm.

As far as stamina, I think whatever stuff he admitted to using was for stamina, not power, which imo contributed to the drop in his punch output.

As his previous fight he not only beat Margarito down, he was the smaller man. Did he age in between?

His best shot was to stop listening to that corner who tried to convince him he could match speed and actually box with Mayweather at that stage. Young or old-ish Shane would do that multi half or throw away jab immediately followed by loaded right hands and Mayweather read the book.
