For PBP purposes, a play is counted towards playtime percentage if the play runs to completion, regardless if the play was nullified by a penalty (e.g., a play that is blown dead by a penalty, due to a false start or encroachment penalties, etc. do not count in this calculation). A play is defined by the personnel on the field. A fake punt or field goal is considered a Special Teams play, and a 2-point conversion attempt is considered an offensive/defensive play.
