I get what you are saying and have no argument against your position, but I do have a question that I hope may be answered here and may even shed some light on the flat footedness of at least the CB....The CB is question, the one on the right sode of teh field was at the first down line, correct? just wanna make sure we're focusing on the same CB....
Now my question is, was there previous information in regards to the ability to move defenders to play in front of or along the first down marker line? Could that be what the CB was doing? I am not justifying his flat footedness, just curious if that may have been an example of this apparent feature of defending the first down markers?
