Two years ago, the only way to watch the Arizona Cardinals’ offense was through a crack in closed fingers — unable to turn away from the trainwreck on the field. The offensive environment that rookie quarterback Josh Rosen was thrown into was, to put it kindly, suboptimal, and Rosen didn’t come close to rising above his circumstances. Their -0.25 expected points added (EPA) per play in 2018 was the worst mark of any team in the past five seasons, falling below even the 2016 Los Angeles Rams.
The Cardinals’ offense got some life last season, though.
