Many people seem to forget that these are still kids and that they are improving. The defense should be much better next year, the front 7 has improved this yearalone and will only get better next year with more guys being able to contribute. The secondary has athletes so the problem is either mental or coaching. However do not expect an elite defense.
The offense should be in good shape regardless. It would help if Clausen and Tate return but we have enough weapons around them to keep it going. We do lose 2 tackles but the backups will be an upgrade in athleticism.
The team will be better next year, but only time will tell how much.
