MIAMI GARDENS, Fla. — Keep an eye on Dolphins punter Thomas Morstead during Sunday’s game against Green Bay. He won’t be hard to spot. He’ll be the guy constantly running up and down the sideline, 30 or 40 yards at a time, while the Dolphins have the ball. Or he’ll be jumping up and down, or stretching, all the while dodging cheerleaders, photographers, game officials, TV camera operators and other such sideline traffic.
Morstead is constantly in motion because he likes to keep his heart rate between 110 and 130 beats per minute.
“If you were to track my heart rate during the game, it kind of looks like I’m running a marathon,” he said.
