yeah his stance stands out right away he sometimes has a majority of his body weight back on his right leg vs evenly over each leg. fighters dont do that anymore thats a bob fitzsimmons stance. i dont think a fighter has to do that but it has the advantage that it maximizes the transfer of weight from back leg to front leg when throwing a right hand, so that 100% of body weight is carried forward with the right hand, sort of like a pitcher throwing a baseball. but i was more interested in his jab like you said he has a rising jab that comes up from the hip which is hard to see because its coming from just under your field of vision. left hooks are hard to see too, for the same reason, that it comes around your field of vision, instead of straight through it, like a right hand, and it can blindside you. its a blindside punch. but that jab was the key in this fight he was whipping his head with that jab. freddie little was feeding jabs to him like peanut m & m's he was landing just about every jab he threw hard. he knocked him out with that big right hand but that fight was more of a jab clinic.
i just wanted to point out one thing. his opponent was throwing a lot of counter jabs when freddie little jabbed. the way to counter a counter jab is to throw your jab, just to activate the counter jab, and then counter it with a right hand over the top. thats how freddie little knocked him out. but the jab is what set it all up. being patient and restricting your punch output to jabs, forces your opponent to plan around the jab exclusively, which makes him predictable, like a pitcher trying to set up a change up, by showing the hitter only fast balls. its the same concept.
