I could see hoffman go through the reads on most of those short pass. you don't look for multiple different receivers to throw a called play. thats reading a defense. also if any offense is to score points at any college level plays must me changed or checked out of. no coach can ever call the right play every time and that is the players responsibility to react to that on the field. so again there are checks being made and the primary receiver is not thrown to every time or there is no way the valpo offense or any offense for that matter can score consistently.
