What we do know is that 250lbs Joshua had a cardio collapse in round 5 with only a minimal workrate expended until that point. It was impressive that he was able to get a 2nd wind late in the fight but that's still a very bad sign. The extra weight in all likelihood will make his stamina worse.
Joshua threw over 200 punches in 5 rounds. That's a decent output for a HW. Followed it up with just over a 100 through the next 5 which is low and ended the fight with nearly 50 in the last round trying to get Wlad out.
He gassed out against klitschko got a 2nd wind thanks to klitschko letting him off the hook his not gonna get that lucky again next time he gasses out and he will coming in like a body builder he will get taken out
to be fair, it's not like the American "feet" and "yards" measurements for lentgh are any more distinguished.
And, to continue the lesson in the mathematics of the imperial unit system of weight measurement, w/r/t one Tyson Fury, 26 stone amounts to 364 lbs.
Yes. Didn't you know? We measure all weights relative to a universally agreed upon lump of minerals that is carefully guarded day and night in the tower of London to prevent scallywags from chranging it's mass and throwing the whole country into disarray. During my most recent meeting with her Majesty the Queen I was rather gluttonous with the tea and scones and found myself weighing a quite portly 13 stones and 5 rocks.
