USC’s fullback who explains his role like this:

It takes a different breed to undertake the fullback role. It helps to have a thick forehead, too. You must constantly subject yourself to high speed collisions that rattle your skull and leave you swatting at gnats that don’t really exist. You must be prone to violence, accept pain as your friend, and sacrifice your body so your teammate can make the ESPN highlight reel.
