One time could be chalked up to luck, an anomaly, or an aberration. But it's certainly hard to ignore something that's been successful four years in a row.
Football Outsiders released its annual study on the amount of "Adjusted Games Lost" due to injury for 2016. The Eagles had the fourth-lowest total in the league at just 38.4 games, behind only Los Angeles, Cincinnati, and Tennessee. Philadelphia ranked first in the NFL in 2013, and has not placed worse than sixth since then. Football Outsiders not only takes the amount of games that players were sidelined, but also factors in their level of involvement because the loss of a starter counts more than an inactive player on gameday.
