Injuries often beget injuries. We know when playing hurt, one can injure a different body part more easily through compensation. When starters get hurt, the backups can be more likely to be injured, too. I call this the “domino effect”. First, the second string has to try harder and sell out to make the grade, making them more prone to injury. Next, non-starters are the backbone of special teams and when they move up on the depth chart, they often take on double duty as their special teams roles continue and fatigue sets in making injuries more likely.
The Eagles defensive backfield is such an example and the secondary continues to fall like dominos. Philadelphia had its share of injuries last season, but the backups were able to step in to help get the ring. This year, even the second line of the secondary is getting hurt.
