Why didn’t AJ land a massive left hook on Usyk

I think he had a wrong gameplan. The second fight looked exactly like the first fight Aj trying to outbox Usyk. If he put pressure on him he would land much more hard shots

 

You can't out position Usyk so in order to land on him you have to pressure him, counterpunch him or time him behind feints. AJ is a trash pressure fighter and not the greatest counterpuncher or doesn't throw good feints. He couldn't use his jab against Usyk which Usyk took away from him in 60 seconds. That's the fight over out of the gate

Usyk made a few mistakes that enabled AJ to catch him with a few bodyshots and uppercuts...but again nothing he couldn't handle.

Fury is different. He throws from odd angles. Can set a high pace. Can pressure mentally and physically. He's fast. He's longer & taller. He's got balls of steel.

 

"Cunningham was a textbook journeyman as a heavyweight."

I see no reason why Cunningham's credentials as a 2x cruiserweight champion should be omitted and unless you have a highly unorthodox definition of "journeyman" that includes champion fighters who always come to win, Cunningham obviously wasn't a journeyman. He was as good if not better as most of Usyk's post-Glowacki CW wins. In 10 HW fights Cunningham has just one definitive loss, to Fury in a war, with the decision losses to Adamek and Glazkov being highly contentious. Cunningham could have easily been 9-1 at HW with more favourable judges.

"Going by his logic, Fury should big Pajkic up as a great victory"

Objectively Cunningham gave Fury a much harder fight in defeat than Pajkic so it doesn't follow at all. Pajkic was the first to put Fury down (a less developed version than the one who fought Cunningham) but he won 1 round and got stopped in 3, whereas Cunningham did vastly better. This doesn't mean that Cunningham was Fury's toughest fight (he certainly wasn't, Cunningham is probably 5th) but he's a more plausible answer than Pajkic, who like McDermott was a domestic level fighter rather than a seasoned champion.

"For starters, Fury also said...Wilder was a bum etc."

Yes, moron. Fury contradicts himself regularly, which is why everything he says has to be taken with a handful of salt.

Rydell Booker recently said that some 30-17 journeyman, on a losing streak, at the end of his career, who he beat by UD, was a "tougher" opponent than Toney, Pulev, Hrgovic, Wallin, who all dominated him. Do you believe him? Is that "Occam's razor"?

Given we know that Fury is a habitual liar with an axe to grind against several opponents, is hanging on his word rather than examining the fights really logical?

 

A combination of things

Usyk is really good
Joshua is too cautious, less so in the 2nd fight but still way too cautious
Joshua got obsessed with being a skilful ‘Boxer’ and has abandoned his wrecking ball nature
