Floyd has shown and proven that Boxing is a thinking sport. Hes the best at what he does. Hes not only the best defense boxer but offensive too. Manny is great fighter too but hes not as good as he was. The best of the best will always have that continuance of improving. Floyd has that right mentality and ambition to be the best. He knows hes the best. Hes #1 in the top 10.

Henry Armstrong in my opinion was one of the greatest offensive fighters of all time.

He was always moving forward and throwing punches.

Manny is a good offensive fighter. Styles make fights and lots of action makes an exciting fight.

If by greatest defensive specialist we can include avoiding tough fights, then Floyd is the best of the best.

People are always discussing the greatest defensive specialists and mention Mayweather Jr, Jack Johnson, Wilfredo Benitez, Pernell Whitaker, James Toney, Willie Pep, Nicolino Locche etc. How bout the most effective offensive fighters? Would Manny be one of them? He to me, is the greatest offensive fighter of this era and Mayweather is the greatest defensive fighter which makes this match-up even more enticing. What do you think? Top 10.
