<b>William Roy "Link" Lyman – </b>Many pro football historians believe that the constant shifting by defensive players before each play in modern professional football can be traced back to Lyman, who regularly resorted to similar ploys. His sliding, shifting style of defensive line play confused his opponents and made him one of the most respected players of his time. Lyman explained that the idea of shifting was an instinctive move to fool a blocker. He had a unique ability to diagnose a play and many times he would make his move just as the ball was snapped.
