Zhang Hao is actively defending, has the conditions for defense, but doesn't know how to defend.
His footwork keeps up, but he's easily faked out.
It's not that he wants to be faked out, he's tried hard, and can get into position during help defense, but his lack of experience makes him easily fooled by the opponent's feints.
This is something everyone on the Brooklyn Nets knows.
Randy Whitman doesn't have high expectations for Zhang Hao's defense either. After all, he's a rookie; having some defensive flaws is okay, as defense takes time to refine.
But this time, PJ Brown noticed a characteristic of Zhang Hao when he occasionally succeeded on defense—he can withstand the opponent's impact.
It's not outstanding athletic ability, and his help defense is actually pretty bad. Getting into position but defending poorly doesn't serve much purpose.
None of the Brooklyn Nets themselves noticed how well Zhang Hao handles external impact, better than PJ Brown and Jason Williams!
