Zhang is, imo, the hardest hitting fighter in the sport right now. Every time he hits grown men, they become petrified boys who looked stunned by every punch. I believe he is in the same class as Foreman and Liston for punching power and, like both men, would beat nearly every pressure fighter in HW history on a stylistic basis. He twice KOed a truly iron-chinned fighter in Joyce and had the cement block chinned Hrgovic running scared at points. So, is Big Bang an ATG HW puncher?
He has ATG power, given how he cracked Joyce's chin. But power is not the only requirement for being an ATG puncher, you need speed, killer instinct, the ability to set up combinations, to create openings, to counter-punch, to position yourself accordingly to throw the best shots possible, and of course the ability to finish the job. I'm not convinced Zhang has all the ingredients to be one, Joyce is about as hard to hit as a heavy bag.
His skills combined with his size and power are what make Zhang unique, but he doesn’t let his hands go often enough during fights for me to call him an ATG puncher. He probably has ATG power, though.
Didn't he show pretty much all these skills against Wilder though? He set him up with the long left hand to the body and jab, cut the ring off on him, forced him into throwing his right hand and countered with the right hook. Once he had him hurt he jumped on him and showed killer instinct. He's not a speedster but for a man his size he still has adequate hand-speed. Zhang was a decorated amateur and has a good skillset and is pretty versatile all round imo.
A bit too early to call him an ATG puncher he stopped the very limited Joyce and a totally shot Wilder who offered no resistance. To be fair he also did show some good power vs Parker despite losing. But I'm not willing to put Zhang quite on that pedestal as of yet, obviously his size is a major factor aswell as being a rare Heavyweight Southpaw with solid technique. But theres been plenty of B class Heavyweights who had good power, I don't see that Zhang has proven hes a bigger hitter than the likes of even Ruddock, Tua, etc.
It's not hard to cut the ring off against Wilder if you're the same size as him, much les 70 lbs heavier. Wilder might be the worst fighter ever when he is on the back-foot. And Zhang can't really chain more than a few punches together, just throwing consecutive punches is not the same as throwing combinations. Wilder literally turned around after he got hurt, it's easy to finish someone off that way, it's really not a good example of finishing ability. I'm not saying Zhang is not an ATG puncher, but he hasn't proved it so far, his overall skillset is very basic. I doubt my position will ever change given his age.
He knocked them both down. The fact he couldn’t knock them out isn’t because he lacks power, it’s because he lacks the stamina to keep a high pace for more than 6 rounds. Zhang clearly has abnormally high power in both hands.
I don't know if I'd say all time he certainly hits very hard. I mean he hardly threw that many punches against Parker but when he did open up he dropped him twice. He doesn't have to put a lot of body into his punches either he seems to throw them from the shoulder effortlessly which I do find commendable he is so accurate with that left He has had a history of stamina issues though I don't blame stamina for the Parker fight because I don't feel like he threw enough punches to get tired. Parker seemed to really befuddle him with his movement his counters and his boxing skills. I watched that fight recently and I didn't get the impression that it was a stamina issue that costed him the fight
