Biff is one of the main characters in the play "Death of a Salesman" by Arthur Miller. Biff is Willy's and Linda's son. He was the star of the football team and had scholarships to 3 college's, but he flunked math and couldn't graduate, so he tried to work at many different jobs, and failed at each. Finally, he decided to head out west, and work on farms. Biff came back home this spring, because he didn't know what he was doing with his life. Willy has mood swings and sometimes thinks very highly of Biff sometimes but other times he hates him ....
