His chin is OK but his heart supersedes all. If his chin lets him down, his heart never does. This was also evident in the Wallin fight, he was cut badly early on and still somehow ground out the win. No one can stop the Gypsy King.
People are overrating Wilders power because he shatters glass. Furys chin is decent but nothing special, imo. Wilders power will be put into better perspective for people once he fights another top fighter. If he KOs Ruiz next, I will own being wrong and start believing his power is more than I thought. As of now I think people are largely being fooled by typical boxing manufacturing. I say this as a Wilder fan. ... Dont get me wrong, not saying hes not a legitimate power puncher or not the hardest puncher in the division, I just think his power is overrated due to smart matchmaking. I think most other historical power punchers would replicate Wilders showings.
Average chin, excellent ability of recovery. Like Ali, you could put him down but keeping him down is the hard part.
As Emmanuel Steward stated back in 2011, Fury's chin is good (2 of Wilder's KD's on Fury involved rabbit punching and very few fighters are taking the shots Fury did in 4 fights with the two biggest punchers Wlad and Wilder without hitting the canvas a lot and/or being sparked out) but his powers of recovery are GOAT.
In the end it looks like a very good chin. People point always to the early KD's but they were big overhands clean on his face so he actually did well to get up and fight on effectively. It doesn't matter if those two weren't KO artists, they landed their best punch. All it really shows is that even guys who aren't big punchers in the division can do damage when they land flush. But most boxers say this so it shouldn't surprise people really. Skip ahead, he took a number of big RHs from Wlad, the one where he nodded afterwards and the one in the last round on the temple in the corner. We all know about the Wilder fights. He also took a number of big left hooks in the first fight too, in the first round and in the final round after the KD. At 17 he got dropped by Price and got up. AJ preferred to sleep it off in the gym. Even though Chisora isn't a huge puncher, he can be dangerous and Fury still took quite a few shots from him in the first fight. Even with Wallin, he's a 6'4 fighter so must have some power. He landed a perfectly clean left on Fury's jaw in the final round Fury didn't see coming. It was almost like a free punch. It did seem to hurt Fury but he didn't go anywhere, just did some weird defensive movements.
Fury is not given enough credit for his chin because he was knocked down. But a knockdown means nothing when the guy is undefeated at the end. So his chin is actually very good, might not be the best, but combine it with maybe the best recovery in boxing, so that turns him into a granite man to beat.
Your overall point is sound, and I appreciate your allusion to all the 'Fury got dropped by _____ so Waldo Klit will kill him even though Waldo Klit doesn't throw the punch _____ dropped Fury with' nonsense we had to read in the first half of the 2010s (and still occasionally have to read variations on with reference to other perceived threats). However, just for the sake of accuracy, it was a mature Price who was dumped on his ass by a teenage Fury in the amateurs.
He went down against Cunningham due to the impact, not because he was hurt. He was really down against Wilder, hardest puncher in the sport, and got up again from a punch that would have knocked out the vast majority of fighters.
Squared up, hands down, chin on a platter, offering Cunningham a free shot to knock him out, not giving a ****. Not to be confused with the alert version who had his hands behind his back and stuck his chin out to bait Wlad and Wilder while ready to slip their fire.
