Ali struggled with swarmers so I don`t think Fury would have the style to beat him, however Ali never fought a fighter with a 85 inch jab so he might have got out-pointed, Ali usually improved in rematches though.
Louis was better than Fury but may have been too small, Foreman could struggle but if it turned into a brawl he could come out on top, Holmes would out-jab Fury, Larry`s jab was far more educated, he was just an allround better fighter, Lewis v Fury would have been messy and close but Lewis a better combo puncher with a better trainer in his corner which would give him an edge.
I think reach would be a factor, Louis: 76 in (193 cm) Foreman: 78+1⁄2 in (199 cm) Lewis: 84 in (213 cm) Holmes: 81 in (206 cm) I think for this reason Lewis and Holmes would land more than Foreman or Louis.
He would get stopped by all except possibly Ali and Lewis, who might just decision him. Depends on how cautious Lewis is.
Ali - Fury W SD Louis- Fury W UD Foreman - Fury W UD Holmes - Fury W SD Lewis - Fury L UD I'm not fan of Fury fan, but I favour him highly over a lot of ATG's due to his size, reach, height & awkward skillset. He beats all except Lewis IMO. Ali & Holmes could outbox him, but won't be able to outmuslce him as they dont have the size or power. This will lead Fury to lean all over them to smother their outboxing. Lewis will be too big & physical for Fury to lean all over & smother. If he does that he'll pay a big price that could get him KTFO. You also left out Tyson who would stop or beat Fury on points (ala the Bonecrusher fight).
Count me in as another non-Fury fan. I find him incredibly over rated. In my opinion, all 5 fighters are victorious. He’s limited as a fighter - doesn’t move, seems like his punches are in slow motion, and he lacks any kind of quickness with his punches. Ali would dance circles around him. Foreman would get an early round KO as would Lewis. Holmes would out box him and won easily on points. Louis would have the biggest challenge to me, but wins on a late round stoppage or decision. Of course, what the hell do I know.
I think they all beat fury. except maybe fury from Wilder II when Tyson was at his absolute physical peak. But Tyson from Wilder III Loses to them all.
