You have to start with the common denominators:
1. Defensive collapses - assignment breakdowns, soft zone D, etc.....
2. Subpar linebacking play (Hurl, K. Knox)
3. Lack of 50/50 ball, D stretcher (opposite Adams)
4. Backup QB who can do a job
The Hall situation is just the first - the rest is on Walters and the scouting....
