On that coverage bust I saw the staff talking to Keontra after. That is what I saw on film as well. He looked to be responsible for the running back. He took more of bee-line to the flat but he initially lost sight of the running back who was going up field.
I believe that is Mario’s quote about “eye discipline.” Some mistakes out there sure, but that is almost a blessing. You win that big but convince the troops there is still much work to do.
