'You're never too old to learn'

Even icons have their heroes.

For four-time Super Bowl MVP Tom Brady, the list starts with his father, Tom Sr.

"My dad has had the greatest influence on my life and career, on and off the field," the New England Patriots quarterback said on Sunday in Beijing. "He taught me to love the game and to never give less than my best. I've been blessed that my mom and the rest of my family have always been so supportive, too. Nobody makes this journey alone."
