The offense also had an off day today IMO. Several missed opportunities that we need to connect on against the better teams. The overthrown ball to Thomas and to Dressen were both big missed plays. That and the fumbles need to get fixed.
That said, SD's defense is a solid D no doubt about it, so overall it was ok, but against the Pats and Texan's you can't leave those points on the field because the Pats and Texans will put up points of their own.
