larry, lots of the greatest fighters of all time weren't well filmed. hell, robinson, the consensus goat, is not well filmed at welterweight. he's well filmed at middleweight, but those fights are well into a hard career, and took place when he was past his best.
the history of boxing isn't all well filmed, larry. boxing was a much more popular and significant sport in the past. if you want to know about the important periods in boxing's history, you have to read in addition to watching film.
greb wasn't well filmed. many of his top opponents were. he fought just under 300 fights, beating 13 hall of famers and several all time greats along the way. his record reads like a hall of fame register. his accomplishments in boxing are without a doubt among the top 10 of all time. if you don't recognize that, it's because you don't know what you're talking about.
I'm in agreement with Larry, here.
For all I know, Sugar Ray Robinson at welterweight might very well be the finest fighter of all time, but, quite simply, there is no way for me to attest to that.
For me to support that claim, I'd need to be able to witness and assess his performances myself. If proof does not exist, then it is simply left to question.
Sure, resume can help support that position, but once again, we're left with the same problem. You have to accept the strength of his opposition at the time purely on the faith of others' words.
How reliable would it be to declare Picasso the greatest artist of all time without the luxury of being able to actually view his work today?
Would it be enough for you to just be told via word of mouth that, back in the day, people who saw his work were really, really impressed?
What if we never had the musical manuscripts for the works of Mozart and his music could never be recreated or heard again.
Would it be enough for you just to know that the people who did get a chance to hear it back in the 1700s heartily declared it the greatest music of all time, never to be challenged?
Boxing is not an objective sport - hence why we have judges. If boxing was more like sprinting, we wouldn't need video evidence.
If the records of history had shown a man to have run the 100m in 9 seconds flat in the early 1900s, it wouldn't matter how that 9 seconds looked on camera, we could objectively call him the fastest sprinter in recorded history.
Boxing, sadly, cannot be afforded that luxury.
So to say, X is the greatest fighter of all time, having seen little to none of his greatest performances is, I feel, a very sketchy position to hold.
You're relying on the strength of other peoples words.
And that's how myths get started.
