What happened: Jared McCain connected from deep for his fourth three-pointer of the first half. He reached 12 points by intermission with Oklahoma City in front at home in preseason play.

Why it matters: The shooting burst paced Oklahoma City's first-half offense and staked the Thunder to the halftime edge. It offered an early look at his perimeter role as the Thunder open their preseason slate at home.

What to watch: Watch McCain's second-half workload and whether Oklahoma City closes out the home preseason outing.
