I think that is pretty darn good. For me, Dubois is #2, as Fury has not won an important fight in 2 years. But I also agree with the Chisora call.
I don’t see Fury’s place as number two justified based on his most recent showings against Usyk and Ngannou. You mention how Fury had more success against Usyk than other HWs but you didn’t mention that Usyk practically knocked him out and certainly hurt him more than any other HWs he fought, despite giving away some 40 lbs to Fury. Also, Ngannou knocking Fury down was simply embarrassing. To be knocked down and only win a controversial SD against a debutant MMA fighter in his late thirties is just not good enough. In my book, both Dubois and Parker are clearly ranked above Fury at the moment.
Usual Fury haters at it again lol Fury is definitely 2 or 3, not lower If he loses December in the rematch? Then for sure, but until then he's top 2 (3 at worst)
