1. Injuries. Yes, every team has injuries but to lose basically your entire pass rushing cast, both starters and backups, plus a Pro Bowl starting cornerback is extremely damaging to your team.
2. Player losses. Lose your starting LT and C, plus two valuable backups in Armstrong and Fowler, plus your main running back in Pollard is again damaging to your team.
3. Failing to sign Henry or all but one good player (Kendricks) to address deficiencies in offense and defense
4. Hiring an old, tired DC that most every OC in the league knows what he will do with the defense to replace Quinn instead of a young, innovative coach.
