These charting articles usually won’t include much in terms of writing but I wanted to clarify some of the specifics that the Nebraska game brought out. The first being junk plays, or plays that are largely irrelevant in the game. A QB taking a snap and then taking a knee in the middle of the field is important for the kicker, but not so important in the average yards per play under center, so it’s not included. The same with quarterback sneaks right before the half.
I also don’t include plays with pre-snap penalties, or post snap penalty yardage in the yards for a play.
