How is it that in the 90s David Tua was throwing more punches than Usyk does?

[Atypicalbrit]

Like when Tua and Ibeabuci threw 1000 punches each against each other.

Usyk is known for his insane stamina and he's a small heavyweight but these guys were 250lb muscle behemoths and threw more shots than Usyk and neither even really got that tired.

Why was that?

[Toffee]

They were 220 and 230. None of that era were weighing in at 250.

And full of drugs.

[MusoMeanderings]

They had great chins and could allow themselves to get hit by a few to land a few.

Usyk can't allow himself to be hit that much by men much bigger than him.

[HeadShots]

They were the same size as Usyk.

mayweather changed boxing. all the best guys are defence first now

[takenotes]

Usyk just has better management of his shots and just does not throw bombs for the sake of throwing bombs.
