If I can figure out how to stop this offense, then that's bad. Take away Witten, close down the running lanes, and the offense completely shuts down. Teams are going to continue doing to do that over and over.
Also, why is it only defensive players taking responsibility for the loss in those tweets? Defense played as well as they could against the Patriots. In order for us to have had a defensive win, we'd have to have held the Patriots to 3 points unless we got a ton of turnovers, which wasn't going to happen.
