Sounds very positive to me. I'd be very concerned if the defense were being carved up by the offense at this point in time. We need a defense who can stop teams and our offense, so much as we know of it to this point in time, will present a lot of the kinds of challenges that most of our opponents will throw at us, shoud get the D ready for the upcoming season.
Some give and take, ups and downs on both sides, is usually a good thing imo. As well as the offense played in the spring game, it is good to see the defense getting a better handle on it now. It is true the defense usually has a head start early in camp but this is a little different with the new schemes etc.
