Give defense some credits. Defense is WIP.

With absence of JPP, DRC, defense managed to generate 3 turnovers.  2 interceptions led to 2 offensive TDs.  1 forced fumble before goal line turned Washington TD into touch back.

While your list of wrongdoings is valid, the defense limited the NFL #1 run offense (after 2 weeks) to non-factor in this game.  Special team TD is not fault of defense.  Pass defense is indeed a concern without pass rush though.
