Whether it's failure to communicate or "understanding ones' job". Either way, it's safe to say this Oline and WR's for that matter lack a lot of talent. So like I said, it falls into the category of needing better linemen. You can call it "bunk" if you want, it's quite obvious the offensive side of the ball needs a few better players.
IMO better linemen would be able to "communicate" or "understand one's job" better. So there is no "just bunk on this play"as you say.It is otherwise "just fact".
