The Good: The man was a throwback personified; he could switch styles of fighting at on a whim at any moment and was versatile throughout. Another great attribute he wasn’t intimidated by the infamous “Mr. Grey” who was a mobbed up boxing insider who paid fighters to throw fights. In fact, to an extent he wasn’t fazed by the mob at all and fought his way to the top despite corruption/politics something not many fighters couldn’t do at that time. I don’t even need to talk about his classic fights they are pretty self evident.
The Bad: It’s said that a lot of his best fights in his early years were never documented on film so who knows how much greater he could have been in seeing with our own eyes his versatility/ fighting ability. Another bad attribute he like so many fighters surrounded himself with people that were just hang-arounds with their hands out. He thought everyone was his friend only to screw him in the end.
The Ugly: You pretty much covered all bases with your post on it.
