Trent Caldwell was nineteen, rocking his weight from toe to toe between strikes in a steady rhythm.

He threw a three-punch combination, stepped back, and drove a heavy right hook into the middle of the leather bag.

These weren’t wild beginner’s swings.

Every punch turned cleanly off his back hip, putting maximum force into the padded bag.

He stopped, wiped his forehead with his forearm, and stared straight through the glass at my face.

He didn’t look away.

He lifted his chin, took two bouncing steps toward the property marker, and kicked the base of the iron frame deeper into the dirt.
