I have been a huge MMA fan since i was 13, but have slowly but surely been getting into boxing and kickboxing understanding the unique skill sets each of these sports require. Now I am starting private lessons in boxing at 17 after doing wrestling, bjj, and some limited boxing/kickboxing for about 2 years. I was told to study up on the history of boxing so that i can become more passionate for the sport and while im caught up on current boxing, who are some fighters i should watch from long ago? All i can really think of is the really famous ones such as rocky Marciano, Joe louis, sugar ray robinson. But are their any subtle maybe not as famous fighters that i should catch up on? Thanks.
