There are multiple things that brought this down and coaching was the #1 thing that sets a chain reaction.
Your coach should never let your team wear the shirt of the backup QB as soon as he switches to the starter because of poor play. Injury? I can see it as a rallying point. It all began there with Wilson and Mike White and it showed everyone that the inmates ran the asylum.
Next was management, and even though Douglas has made some great picks, there are too many other flaws. He never fixed the OL and never got the QB situation correct. Tried to address both and failed mainly because the OL couldn't block.
Went with a nearly entire staff in year 1 at their new job. No veteran coordinator for a rookie coach to lean on. It showed in player management the most.
And now you've got a talented roster without a coaching staff to get the most out of them. The issue wasn't just Saleh, it was the whole group, from top to bottom.
And now it was basically get Rodgers whoever he wants. The team needs a cleanse and unfortunately it probably means some of these talented guys do leave, but it's not going to work.
A real cleanse would be Woody Johnson selling the team, but I don't think that will be on the table anytime soon.
