I spend most of my time dealing with boxing history and in my view this concept of best pound for pound fighter is pointless. The phrase was coined to describe one man, Sugar Ray Robinson. I think it is virtually impossible to compare fighters from different eras, however until someone is 135-1 or 220-1 counting his amateur career, before losing his title, and wins the title back in the 137th pro fight I think the phrase should be reserved for what it was intended a description of the great Sugar Ray Robinson.
Like so many facets of our society between 24 hour news and 24 hour sports and 3 year presidential campaigns the media creates a huge vacuum to fill and they fill it by overusing and diluting all praise or disdain. Someone or something is always the greatest of all time, the best pound for pound, the fastest, strongest, the worst, the most tragic, the most talented until the next one comes along.
Here's to the truly remarkable career of Sugar Ray Robinson.
