Muhammad Ali is the 2nd greatest boxer in history

Why Sugar Ray Robinson is the greatest boxer in history

Few impressive facts about SRR
-Robinson was 85–0 as an amateur with 69 of those victories coming by way of knockout,
-From 1943 to 1951 Robinson went on a 91 fight unbeaten streak, the third longest in professional boxing history
-He then became the first boxer in history to win a divisional world championship five times (a feat he accomplished by defeating Carmen Basilio in 1958 to regain the middleweight championship).

Muhammad Ali is a close 2nd

[N/A]

Boxrec says Mayweather was better than Robinson.

[Chrismart]

Always a tricky debate but I certainly wouldn't argue with those 2 as the top 2.

[fabie]

I would put in A1 and A2 in both boxers...much like Joe Montana and Tom Brady as A1 and A2.

[Larry the boss]

That is how Ali himself would have had it
