Per Rittenberg at ESPN, at least there's acknowledgement that last week's coaching errors were, in fact, coaching errors:

Ferentz on what staff can do better: "Clearly, we weren’t prepared well enough last week, and we didn’t play well enough as a result."

As for starting quarterback James Vandenberg, who went 16-for-25 for 215 and a score this week, but struggled mightily in the second half and has not looked like he wholly grasps the Greg Davis passing scheme (per Steve Batterson of the Quad City Times):

#qctimes Ferentz on V'berg:"He has played well, but we haven't played well enough to win twice. That's the way it is for James, our team."
