But football is his first love. "You have to become a warrior when you're on the field," he says. It is hard to think of Diana, who has all the meanness and rough edges of a puppy dog, as a warrior. "That may be why I enjoy the game so much," he says. "I expend all my warlike tendencies in football so they don't show in real life." Last week he showed a visitor a film of the little dance he did after a 35-yard touchdown run in the Brown game. He wanted to prove he was capable of displaying emotion on the field. The dance was emotive, but Diana noticed something else in the film. A few yards from the goal line a Brown tackier desperately dived for Diana's ankles. You could see Diana make a tiny jump that was perfectly timed to elude his pursuer's grasp. "You know, I remember seeing that guy," Diana says, running the film back and forth several times. The man was clearly behind him. "I saw him, though," he says. "I don't know how, but I saw him."
Diana studies running backs like Earl Campbell and Walter Payton almost as assiduously as he studies physical chemistry, so maybe it's-not so hard to understand his success at carrying the football, even with his lineman's body. "There's so much you can learn just by watching," he says. "I have a knack for observing and absorbing and then applying things I see to my style.
"When I carry the football, there's such an exhilaration going through my body. I've hit home runs and made great catches, but there's nothing in life that can compare with carrying the ball. I love playing football so much that it hurts me to think that in eight more weeks I might not play anymore."
