Okay, My take. It looks like you had a strong-side power run, and flipped the run to weak side from looking at the playart and the screenshot. This correct? In this run concept, power, the pulling guard always targets the force defender not the B gap.
It’s suppose to be end man on line as the basic concept goes, but the game doesn’t have that logic, instead it cheats and targets the force defender which makes it work correctly in most situations but not this time. If you study it closely you can even see the head of your guard focused on the safety who is force in the run fit; when that safety adjusted his angle so did your guard. It doesn’t help that the weak side had the least amount of leverage for this play to work and that’s exactly where you flipped it to as well.
To be fair, and I’ll preface this to say that I’m critical of the game in many respects including blocking, this run probably shouldn’t have been called against this front. In the future, if you see cover 4, audible to man or zone blocking plays for more success.
