premise: Steve Sylvester (born March 4, 1953 in Cincinnati, Ohio) is a former American football offensive lineman who played 9 seasons in the National Football League for the Oakland/Los Angeles Raiders. He played college football for the University of Notre Dame.
hypothesis: Steve Sylvester played guard and center for Notre Dame.
reason: it does not say what position he played at Notre Dame and it says he was a lineman which I think confused the system
