Wilder has pretty decent stamina if you ask me. He just got hit too many times and it drained him. Wilder has miles better stamina than the likes of Juicy J and Whyte . Juicy J gets panic attacks when the going gets tough and Whyte is pretty much a slob. Id say he is definitely above average in the stamina department. Fury can just plain fight for days. Fury could probably last longer than most when he was 24+ stone.
His stamina at 238lbs was poor he looked tired in the 5th after the effort he but into the 4th, much like how Joshua gasses after a big effort. But when he's fighting closer to his natural weight his stamina does look fine, he's no Vitali but he's not got any real stamina issues unless he bulks up too much.
decent and above average are good at a certain level. At the utmost highest championship level you will get found out with it.
Wilder shouldn’t have weighed no more than his usual 210-220 his legs aren’t steady enough to carry anything more than that.. That body attack in the first 2 rds sapped his energy too much.. Those hooks were a little bit slower due to the extra weight..
210-220 Wilder stamina is good, makes late rounds quiet easily, it was expected for wilder to gas out this fight, I thought around mid rounds but he looked tired after round 2
