We could be a good team. There is probably a deficit somewhere that is directly affecting other phases of the game. I say probably because it's hard to tell when the results point to deficiencies everywhere.
The best way to pinpoint the issue may be to go back to the first games of the season, when everyone was healthy and mentally sharp, and look for the biggest problems. If we do this, we can see that the o-line is a major problem.
An inept offense puts heavy pressure on the D, fatigues the players both mentally and physically - which could lead to injuries and some of the untimely penalties and other miscues.
I am a Dobbs fan, but I think he has been mishandled in a terrible way. Instead of focusing on his strengths; his mobility, there was an attempt to change his on-field presence by training him to become more of a pocket-passer. All year it has seemed as if he waits a moment too long before doing what he has done best - escape the pocket and pressure. It seems he has been coached to stick with the pocket and reads longer than his instincts tell him to. I think this has resulted in much more pressure, a less effective Dobbs rushing attack, and magnified the atrocious O-line play.
It would have been nice to see the playbook molded to the player's strengths, instead of molding the players into something different in order to run plays they are not suited for.
The bigger issue with this sort of coaching is there is no quick fix. Changing the fundamental development of a player takes time and it takes time for them to revert to their natural ability - if they ever can. This could explain the slow starts in many of the games, as it takes time for the player to abandon what they've been coached and rely on their natural ability and instincts.
If this is the case, then whoever decided to takes this route in his development needs to have a serious review of their place on the coaching staff. If there has been such a terrible judgement made, then it's reasonable to believe that there have been more extensive poor judgement decisions made in areas that are not as obvious, but compound into the offensive circus we've seen and directly contributes to the other major problems.
TLDR; It's offensive coaching.
