One is not exclusive of the other...
Of course not, but the offense has been much, much better than the defense this year. I do agree that the defense played a bit better yesterday and has improved slightly since Sawvel was let go. I also agree that the offense hurt us some yesterday, but in my opinion it was the turnovers way more than anything else the offense did or did not do.
The offense is averaging about 225 yards passing and 225 yards rushing per game, which is really solid production.
