15 rounds, maybe the hardest hitting middleweight ever vs maybe the most durable middleweight ever, who wins and how?
LaMotta by 13th round kayo. Julian finds out early he can't hurt Jake and it goes downhill from there.
Julian is too big for LaMotta. Even at junior middle. Jake liked his ‘middleweight’ opponents closer to 148-150 while he would come in at 164-166. If Julian drained down to welter Jake might take this fight.
Jackson was more powerful than anyone Jake ever fought and he had fast hands, coming forwards v Jackson was suicide unless you were bigger than him.
Jake never fought such a Top & Dangerous BIGGER L-HW and that is EXACTLY what Jackson would have been in the 1940s... people seem to forget such realities when making these fantasy matches - Modern Now verse Back Then. a fighter the size & stature of Jackson is NOT going to go against the NORM of what all his peers were/did then. there were very few 5' 11 or taller middleweights, fighters that size were L-HWs and finished as HWs. Stop looking at what fighters compete at Now, look at their Stature and remember when Not Fighting, they are weighing 2 & 3 weights heavier than the division their competing in today, which is exactly where they'd have been fighting at Then. J Jackson is a L-HW cum HW - THEN and too much for Jake, sorry.
More powerful than Murphy ,Satterfield? The only name middle Jackson stopped was Graham . The other names ,excepting the moderate Thomas Tate, either stopped or decisioned him.
The match up pre -supposes that both men enter the ring as they actually were, not as some hypothetical projection from a posters creative imagination.
Ignoring TODAY's Fighters Actual Stature and believing they wouldn't be fighting in a Higher Division Then - that's Imagination.
Jackson was a light middle /middleweight throughout his entire career that is a stone cold fact.H2H matchups on this Forum, unless otherwise stated are between fighters as they actually were in the ring in their own era,that is also a cast in stone fact. There is zero evidence ,indication,what you will, that Jackson would have opted to go up the weights ,all the way to heavyweight as you have suggested .The fact that the best of the 160pounders he faced bombed him out suggest it would not have been a wise move on his part! There have been numerous middleweights at 5 feet eleven, many of them recently, many of them in the past, if it would be a viable ,not to say financial proposition , why haven't they all taken the route that you suggest Jackson would have done? There is zero logic behind your argument.
