Taking cues from Michael Jordan, one of his idols,
Bryant played with a swagger that compelled him to talk trash,
to guard the toughest opponents,
to play through pain
and to demand the ball at the biggest moments of games.

應該是要球(準備單打)的意思也可以理解為"跳出來接管比賽"

主宰球賽demand(控制=主宰) ball(球賽)在最重要的時刻主宰球賽~

若你打過籃球的話，應該知道在關鍵時刻向隊友「要球」，需要多大的勇氣，所以大概就是「承擔重責大任」的意思
