ball and also telegraph you're running by the way you line up then yeah that is play calling. It was so easy to see on each one of those failures that A. they were going to run the ball and B. where they were going to run the ball. If the defense knows this as well (and I'm sure they did) then it's easy to stack the numbers in your favor so that there are too many guys to block compared to number of blockers where you want to run the ball which is what happened repeatedly.
