Maybe it's just bad luck. The Indianapolis Colts obviously had far too many injuries to key players, and that affected the season. That isn't the only reason Indy isn't making the postseason, but it is one reason. But is there a chance that the team handled the situation incorrectly and put players in further harm?
To be sure, a player missing a game because of injury isn't only up to the football minds of an organization. The team's medical crew is involved, as well as input from the player. No one knows better how a person is feeling than the person themselves, of course.
