Physically you figure Fury would be problematic for Joe. On talent, it's hard to say cause no one Fury has faced can tie Joe's shoes. I'm thinking to myself, what's bigger - the size gap, or the quality gap? Probably the latter. 71 Frazier breaks Fury down IMO.
It'd either be a complete butchering where Joe mangles his body; or it's a horrible match where everything is messy and there's a lot of holding and lulls in the action. Either way, I take Frazier.
If we're talking about the Frazier from FOTC then I can see him being too relentless for Fury and beating him on points. At the same time I can also see Fury beating Frazier if he decides to fight negatively or using his size to grab and maul Frazier to win a sloppy decision. The question is if Fury is able to withstand Frazier's left and not go down.
