I've seen this same thing happen with the Vikings over the past 5 weeks or so. Coach Childress lost the players a few weeks ago and they started looking out for themselves instead of playing hard. With Childress it was his over meddling in the offense and trying to control Favre instead of letting him just play. With Childress it was the open and public criticism of the players and painting them into corners. With Ferentz, I think you guys are right, it is more his unconcern for the players (holding, chop blocks, helmet to helmet hits, etc.) that has lost them - not to mention the same kind of shackling on offense (and apparently on offense - as some are talking about the bull-rushing only in order to stay in certain lanes). Anyway, I see so many similarities between the hawks and vikes right now.
I think the vikes are going to turn it around because they took out the butthead that was the head coach, and now the offensive coordinator can actually do his job and Favre can run plays they've actually practiced before. Something has to change with the coaching staff, or this same level of apathy will continue into next year.
A few years ago, Ferentz was able to fire up the players by poking fun at them and calling them "fat cats." I think if he does that now it might just backfire on him. I think its time for him to make some changes in his own approach or in his coaching staff.
You look at a guy like Adrian Peterson - all the talent in the world, and his coach can't give him an open running lane or get him to the outside. When Adrian was running into a wall of defenders every play, he's going to stop trying as hard. And AP is more stand up than the rest - I don't know how much he's given up. But you can see it at nearly every other position- particularly the offensive and defensive lines. I think the same thing has happened with the Hawks. The O is banging their heads against a brick wall nearly every play...its not working...they're going to stop trying so hard. Its human nature.
