Prime RJJ's weaknesses.

[Andre]

I'm sure from a trainers standpoint and based on the fundamentals used for fighters that are not him, he did everything wrong.

theres this boxing myth that roy did everything wrong. if roy did everything wrong then jimmy mclarnin did everything wrong. benny leonard did everything wrong. charley burley did everything wrong.

this narrative that roy breaks the rules of boxing or that he does things that have never been done before and only gets away with it because of athleticism is just flat out wrong.

Theres a big difference between doing everything wrong and breaking all the basic rules cause you can. Its just another level.
