Calling BS on a poster know for it. Jeffries floored Ruhlin in rounds 2 and 5, and was in control from rounds 3-5. At best for Ruhlin after 2 rounds ( who says so and so was in the lead after 2 rounds anyway ? ) it was even in rounds, or scored under modern rules, Jeffires in the lead. This guy knows how to break down flip, he write " As witnesses testified, Ruhlin was outclassed from the start and Jeffries spent much of the fight in pursuit. But there are some vivid moments of the champion during the exchanges that show what a dangerous fighter he was; including his speed, power and ability to cut off the ring." https://fightfilmcollector.blogspot.com/2013/10/jim-jeffries-champion-lost-and-found.html
I'd have to go with Fury here. The lack of footage probably hurts Jeffries a lot, but, that said, Jeffries will be nothing that Fury hasn't seen before whereas Fury would be a complete outlier for Jeffries' times. Best for best you have to favour Fury, I think. Jeffries might be able to beat a garbage version of Fury, which we have seen before eg vs Pianeta.
Jeffries, he went to the body and had Gus on backfoot all round until Gus got dropped. Jeffries landed more and landed heavier punches, that's the definition of boxing.
Chisora is listed at 187 cm with 188 cm reach. Jeffries is listed at 183 cm with 194 cm reach. The difference in height is small and basically unimportant in this comparison. Chisora has a lot more fat than Jeffries, I don't assume that this fat helped him against Fury. Realistically, Jeffries could fight at over 220 lbs (with shorter fight maybe even over 230 lbs) and still look fit. They are the same size basically.
Fury in any timeline I haven’t seen enough of Jeffries to give him a fair shake but his style and lack of throwing many punches (and wrestling) wouldn’t bode well w Fury. Even in a 20 Rounder Fury is a smart man and paces himself well enough for a fat guy
Mcvey sources, ages, and data are often BS. He'll pick and choose a article or passage out of a book for his agenda and omit the rest. Jeffries vs Ruhlin II was an easy fight for Jeffries. Jeffries topped Ruhlin ever taste retain Fitzsimmons did. I still think Fury, though talented has a thin resume. He's beaten a very old Wlad, and an over rated Wilder who cannot box or take punch. The meat on his resume is thin after those two with Chisroa being maybe his 3rd best win. If Fury can beat Joshua that will be his best win. Fight Usyk, and one of the top up and coming heavies who on ability are far better than some in the top ten today, then he'll be recognized as a good champion provided he wins those fights I think Joshua drills him. We'll see. Fury's game is being mobile and long. Vs a man close to his size that puts pressure on his with accuracy, I think he's in trouble.
There is film of both fighters. If you cant see what would happen, that's on you. Just one observation is I've never seen a heavyweight champion that begs to eat a right hand like Jeff does. Wide open. Definitely not on records or contemporary opinions. Think about how many tough guys have a reputation as such... Everyone they know or are associated with will tell you they're tough and believe their toughguy would beat such and such... Then they get beat up. Levels. Jeff had a reputation and for good reason back then. How many toughguys like this have gone to a boxing gym or even a toughman contest and get beat up? Countless times.
Who is the better boxer in what you have seen? Can we compare them as they actually were rather than use some hypothetical versions? This is like Rocky fans saying, well today he would be 210lbs and stronger, in other words BS.
I already answered - Jeffries. But unlike with Rocky, we've seen Jeffries fighting above 220 lbs. Even without any hypothetical versions, he weighed 227 lbs against Johnson and didn't have an pound of fat on his body. He weighed even more against Munroe. This is not fantasy version of Jeffries, he could carry the weight up to 230 lbs very well.
