There are parts of a few of his WW fights out there, or at least used to be. But all in all, there is very little prime footage of SRR.
Unfortunately this footage may have been pulled. You can see in some of his early middleweight bouts the guy is a god in the ring, an absolute war machine. He could have outboxed people all night long with his speed and brilliant jab but he loved taking it to them as well and looking for that knockout. https://www.boxingforum24.com/threads/sugar-ray-robinson-prime-footage.659399/
These videos compile a string of his fights from 1946. This was likely SRR squarely at his peak. This content is protected This content is protected vs. MW Georgie Abrams from '47: This content is protected Title defense vs. Bernard Docusen in '48: This content is protected
To claim Ali is overrated and at the same time saying Mike Tyson is the BOAT is really funny, I gotta admit.
