Our play demonstrates we are less than the sum of our parts. New coach fixes this problem but the change may not be instantaneous. I think if we hire an experienced coach, known for their defensive rigidity, the players will have a lot to forget while trying to learn a new system.
This change needs to happen now. We cannot afford to be absolute shit this year only to make this change in the summer and have this process begin next training camp. If we bring in said coach and have this start how, everything will be in place for a competitive season next year.
The absolute worst case scenario is staying status quo and relieving DJ of his duties in the summer, simply because the solution isn't any different than it is right now. This solution obviously relies on us hiring a long term coach, as an interim coach likely becomes the new worst case scenario.
