Too much turmoil in the roster. The injuries haven't helped. A good OL needs time to gel and become a solid unit. I disagree that Juan is a bad coach. I disagree that we don't have the talent to have a great OL. I think a healthier mix of run vs. pass will help the line. The predictability of our offense lent itself to DL and LB's to pin their ears and come after us. We have to get them to respect play action. We need to get Joe back under center more.
I also believe it is more about chemistry than ability right now........not with every player we have now.......we have the ability on the roster. We just need to find the right mix and settle people into positions. Game to game changes in position isn't helping this situation. With injuries, it just cannot be helped all that much.
If we don't trust Hurst to play Tackle (ergo last week) he needs to be let go and another backup Tackle brought in. If a guy throws a bad game, and you put him back on the bench, it doesn't help with keeping a player/unit consistency present. Analyze the struggle and see if a change in scheme might help the situation (receivers/TE chip blocking). Sometimes its all about matchups! You get faced with a pro bowl caliber edge rusher or DT, you need to address how you deal with them more effectively.
If you cannot handle standard NFL talent after you've EARNED (don't want to say "Given" or someone will go off on me again :-) ) a shot at it and proven that you are not improving or simply cannot handle it (by more than just a handful of games here and there), then to the bench or even to the trade block/cut.
Combat the pass rush by making it a risk to sell out on doing it by defenses. The more 2nd, 3rd and short situations our offense is by running the ball effectively, I believe we'll see better results from the OL's ability to protect Joe.
