It's an interesting one because the Saudi crowd aren't easily duped and if there's obvious signs of carrying, I think they'd prefer the KO.
If Francis is blowing badly it'll be hard to hide and we already know Fury has a massive tank, so he'd have to slow his output considerably for Francis to keep up, but is that going to lessen the 'spectacle'?
I guess it depends on how N'Gannou himself plays it. If he's slow and tentative, it could go to your desired distance, but if he goes for it, two rounds just seems like an organic end. The other caveat is if Fury does indeed go to war as he's promised to do; if N'Gannou hasn't prepared for being tied up and leaned upon, he's in for a shock and probably a heavy uppercut KO.
There's just so many ways for Fury to end it quickly and I can't help but think it'll be too tempting to set Francis up for a sweet counter KO and then begin promo work for Usyk. With that fight in mind, there was speculation on whether Fury will want a quick wrap up, too.
But this is Fury, so expect the unexpected, probably!
