As we move closer to releasing Football Outsiders Almanac 2016, we'll preview some of the charting data which appears in the book. We have already done some of this with passing plus-minus, receiving plus-minus, YAC+, and adjusted interceptions. Now play-action passing is next on the docket. Last season saw some unusual trends across the league, as well as one offense which enjoyed by far the largest improvement we've seen the past five years. Information on play-action usage comes courtesy of ESPN Stats & Information.
