Rewind almost exactly one year ago. Following a Week 3 loss last season, the Dallas Cowboys offense was put under the Football Outsiders Film Room microscope. Under then-offensive coordinator Scott Linehan in the first three weeks, Dallas was using a majority shotgun offense that used three or more receivers on 73% of their snaps despite sporting an awful wide receiver corps. Three-plus receivers and majority shotgun usage is fine in a vacuum, but not with the personnel they had at the time. The Cowboys also were in the bottom half of the league in play-action passing to that point.
