On what do you base Jackson's lack of chin? The fact that he was stopped in his 10 th fight by the Australian Heavyweight Champuion,or the fact that Jeffries stopped him when he was 37 and had TB and was a hopeless alcoholic,he was only dropped one other time by Goddard who kod Choynsky twice and also Peter Maher.
Sorry. I wrote that at work and did not have enough time to respond. I see no evidence that Jackson had a bad chin, just that big, strong punchers seem to be the type that gave him problems. Moreso, we have much less non-anecdotal evidence of Jackson's career than of Jeffries'. A lot of no decisions, a lot of repeat and inexperienced opponents, some wobbly, documented performances against the bigger guys, a very big win against Slavin, a draw against Corbett and a loss when he was depleted against Jeffries. Just no enough to draw drastic conclusions. Also, in regards to Goddard, I have read he KD'd Jackson several times. And in regards to Maher, it was a right of passage to knock him out in those days, so no great accomplishment. In regards to Jeffries, I probably rate him as less impressive than most but that may be another topic.
I think Jackson went down more. No way Jackson had a chin like Ali did. I don't think Jackson's chin was poor, but I don't think it was great either. Jackson was built for speed, and those types usualy do not have good chins. Ali was also built for speed, but he had a pretty big neck, and frame to take a shot.
Again, a proclamation that is difficult to assess. We know quite a bit of the conditions surrounding Ali's KD's and the quality of his opponents. We know far less about the same regarding Jackson. Thus, your statement is more speculation than informed analysis. Nice try, though.
I was really responding to Mendoza's assertion that Jackson didnt have a top level chin,since he was only stopped twice once when 22 and again at 37 ,I would hazard a guess it was pretty durable,you are right though it is speculation on my part,sometimes the record books are all we have to go on,though there is a guy asking if anyone saw Jeffries fight ,I would take a chance and say any ringsiders at Jackson's contests are probably deceased.
I didnt say Jackson's chin was as good as Ali's ,just drew attention to the fact he was only down a few times and stopped twice.Prime jackson at 6 1 1/2 was over 200 lbs, I dont know what his neck measured but he wasnt a slim Corbett type.
Jackson also beats every black fighter who ever lived, too. Right.....but he did have his problems with Corbett... Jackson was a top contender of his day, but was kept from challenging champion John L. Sullivan because of his race. In response to a statement made of defending against a black man, Sullivan stated, "I will not fight a Negro. I never have and I never shall." Despite Sullivan's decision to not fight Jackson, another contender in James J. Corbett fought Jackson in an epic encounter in 1891. The two fought on even terms before a no contest was called after 61 rounds. Corbett would cgo on to defeat Sullivan for the title the following year. I did not know he had the flue, and a twisted anckle here. Nor he was dying of TB vs Jefferies. I am on the earth to learn, amoung other things. I think Jackson at prime would have been a good fight vs anyone, just like a Prime jefferies would have been a good fight vs anyone. Jefferies did not like the style that his trainer made him learn, let them beat up on you until they are tired...He at least got out of it with his moeny to buy a big farm. I think really the main problem was Jackson did not have a rich enough gang of supporters and I do mean gang, to put up the side money for Sullivan. It was the side money and the bets from one gang or another of gamblers that made the fights happen back then.
