While Penning got beat again on an inside move and Ruiz got humiliated by a linebacker, the biggest problem with the offensive line was playing as a team in pass protection. They are bad at picking up blitzes and really bad at picking up stunts.
Given the really bad protection, I don't understand why they insist on dropping Carr straight back every time. They need to change the launch point from play to play and not allow the defense to tee off on one spot. That should give a bit more time for something to develop downfield.
