Popular for both his on-the-field play and his characteristic hairstyle, Pittsburgh Steelers safety Troy Polamalu is another perennial fan favorite. Last year's jersey sales leader continued his momentum this year, and it's easy to see why. Pittsburgh is a blue collar town, and Polamalu is a blue collar player. With Ben Roethlisberger's troubles, most new jersey sales in Pittsburgh are Polamalu's number 43.
