re: Anyone else worried about the defense?

yep. the defense doesnt trust the guy next to them to do their job.

it was glaringly obvious during the outside run play early in the game where arden key started the play in a great position to contain the play to the inside where 2 guys were in position to make the tackle, but then key inexplicably also ran inside because he didnt trust the guys inside to make the tackle when he saw the handoff, then the rb ran right where key was originally standing and the play was designed for him to be for 11 yards. all because he was worried about the guys in the middle not making the tackle. Aranda is proven to know wtf he is doing, the players need to do their job not try to improvise what they think they should be doing instead
