This guy is a throwback to another time in history when fighters were fighters. These guys used gloves that weighed 8 & 10 oz packed w/ horsehair (you can still fell knuckles through modern 12 oz boxing gloves if a guy has big power). Having looked at some of his fight footage in the past, this guy had fighting in his blood. He had a solid chin, good hand speed, & good power. What he lacked in technical skill he made up for in heart. That is one of a few things for which you can't train a fighter. This guy was a classic fighter's fighter. This is the kind of fighter who got hit, looked the other guy in the eye & said "If you think that shit hurt, watch this!" Boxing was a crooked sport in those days. Nobody w/ any sense will argue that, but guy's like LaMotta were a one-man wrecking crew. He didn't come to the ring to pussy foot around & showboat to the crowd. He came to work to whip a man's ass & collect the fat end of the purse.
There was no such animal as a sissy-ass points fighter looking to "game" the game. Incidentally, I'm coughing & thinking of Floyd Mayweather. Mayweather generally fights a perfectly executed game plan; get your punches off, run & reset. Guy's cut from LaMotta's mold just keep coming & coming, relentlessy beating your ass until they put you down. You could literally stand in the middle of the ring & bang w/ a LaMotta type fighter until one of you falls & is unable or unwilling to get back up. It's no wonder that these types of fighters would pack arenas. The LaMotta's of the world are sorely missing from the fight game in today's world.
Rest in peace Jake.
