The reason ODLH stopped throwing the jab, was because he was getting tagged with right hands over the top. And ODLH was rocked a few times by Floyd Mayweather Jr, so he become more cautious with the jab, which in turn is why Floyd Mayweather Jr took tactical command in the later rounds.

As for prime for prime ? i still think Floyd Mayweather Jr wins, he had a great jab at the lower weightclasses, he was more offensive, had more power, and was even quicker.

If a prime ODLH was totally out jabbed by Ike Quartey, and was totally confused by a on the slide Pernell Whitaker's defensive skills. Then for certain Floyd Mayweather Jr takes it again.

Remember Floyd Mayweather Jr wasn't at his best weight above Welterweight, and ODLH had a huge weight advantage something like 1 stone.
