 Schulz recalled that the first time he stepped back from the line on defense , Coach Yost was horrified . Yost said , " Dutchman , what are you trying to do ? " " Stop ' em " , replied Schulz . " But you 're supposed to play in the line " , Yost insisted . " They 'll run over us . " " Listen Yost " , Schulz claims to have said , " My way is best . If any of ' em gets by me , I 'll move back into the line and stay there " . Yost eventually saw the wisdom in Schulz 's technique , and soon nearly all centers were backing up the line on defense .
