The defense played admirably all things considered. I’d fire Dorsey tomorrow and see if Brady has the juice to turn the season around, even if Dorsey isn’t the problem. Need something.
That said, the issues with the defense (old and injured) are structural in nature. We don’t get to chalk them up to bad luck. It’s the oldest defense in the nfl. Injuries and declining play are to be expected. They need to blow it up and start over in the off-season. If you’re going to be mediocre, at least be young, cheap, and mediocre.
