There were no stunts on that play. The Rams showed zone run right then the RB cut back inside. The 1-tech flowed to the play-side as required in the scheme. The 3-tech was on the backside and fell down. This was the primary fail. Vander Esch got boxed out to the offensive-right on the same side as Jaylon which should never happen. The 3-tech falling down made it easier for the OL to get out to block Vander Esch. The 3-tech on that play was Caraun Reid. He is now out of football. He was signed, cut and re-signed last season by the Cowboys. The play demonstrates my basic point. The 1-tech was flowing to the play-side when Rams showed outside zone run to the right. Move a LB outside the LDE, have the LDE squeeze the gap inside the RT (play-side B gap) and the 1-tech can play straight ahead instead of sideways. The backside DT (3-tech) fell down in part because he was moving sideways.
