How much blame do we place on o-line coach Chris Strausser?

The offense is a mess from top to bottom whether it be blocking schemes or not playing players to their strengths or poor coaching, etc.. but I don't see Strausser getting a ton of hate. Colts fans rejoiced when this guy was fired iirc. O-line's technique is awful and they get out of position way too often and continue to kill drives with sloppy penalties 2/3 of the way through the season. They're uninterested and don't have the fire in them they had last year. The homer in me thinks Scruggs could still have potential but he needs a better coach I think for that to even be possible.
