HOUSTON — In the Rockets' final huddle before entering the arena, James Harden implored his teammates to take advantage of this opportunity, to be aggressive from the opening tip. It was minutes prior to Game 7 against the defending NBA champion Golden State Warriors. Harden has always wanted this moment. This opportunity. This drama. He believes he is built for this. The Rockets believe he has this in him. These bright shining moments, when star power often carries the day, can be, should be, his.
