Every team deals with some severe injuries and nagging injuries. However, with all the multi-week and/or season ending injuries this defense has experienced this season, at some point that has an effect on the mindset when they are on the field. This is something that is impossible to keep from creeping up in the back of their minds when they are on the field. And purposely or not, it does have an affect on how hard they go each play. It's human nature. I've been there before; and I'm sure several others have as well. You still get out there and play; but subconsciously, everything that has happened is there.
