Super Bowl LI

21-0. Then 28-3. Last round. Bad cuts above the eyes. Time running out. The old champion sags against the ropes. Jab, left hook, right cross. Knees buckle. Out on his feet. Hits the canvas. Rises at the count of nine. Waits. Collects himself. Parries the next right hand and unleashes his own hook. The challenger goes down. Count to ten. He is out. The champion's hand is raised. Still heavyweight champion of the world. It is the heart of a champion that continues contracting.
