I presume Kubiak knows a lot more than I do, but seeing his comments as well as others in the thread I’d say the answer is all of the above. I’d make these points:
1. Our O line stunk, and even those with a modicum of understanding of the nuances of football could see that. Terrible run blocking and we cannot adjust the blitzes a lot of times (might also be on Josh).
2. WRs. Our WRs do struggle to get separation, and we really miss Palmer in that regard. Plus when Josh was rushed they did a terrible job adjusting routes or working their way to an open spot on the field. It is not the group per se; the only major difference from last year is Hollins and that can’t be why this group is so non-effective.
3. Josh. It seems to me he is hesitant at the line and not sure what he sees in the defense. As a result he is hesitant about where to go with the ball, and as such is not seeing guys that are more open where he can make easy completions. I don’t place any stock in the marriage affecting him stuff, but he does look like he is getting confused and frustrated out there, which leads his to try and play hero ball too much such as with the sneak and fumble that essentially ended the game.
4. Brady. This to me is the biggest problem last week, and in the other losses. He does not adapt well at all within games and he gets away too quickly from stuff that works. I keep talking about two things from last year: the 4+1 alignment and using Ty Johnson as a receiver. Both highly successful last year, neither used much this year. When we pulled that dumb 4th down play I knew it would be a long day.
Just an overall horse hockey performance by everyone associated with the offensive side on the football.
