Some of that is not true (varied pace, footwork, misdirection) and in the end it's the same tactic played to equal effect.
Puka doesn't have significantly less athleticism than Harden nor does he have more "game sense" than the latter. This is the epitome of stereotypical, racial bias analysis.
They lessened the contact/physicality even more so that players like them could thrive even more.
I'm saying, Gobert's impact is of course lessened defensively (though not to the extent you or the masses make seem) with someone like Puka because it doesn't play to his strength.
