Was it the recievers?

Just trying to nail down what the biggest factor was in todays loss? At first it's easy to blame the defense especially after giving up that drive at the end. However they forced 2 turnovers and held them to under 20 points basically all game.

The offense was obviously the issue and maybe blame needs to be shared. Oline not winning on run plays, play calling multiple sweeps which got stuffed, CJ having an off day but imo the biggest thing I noticed was lack of good WR play. Multiple drops, Stroud actually had a lot of time to throw the ball and there was multiple instances where he just had to toss it away. It was evident after Dell went down no one was winning. Thoughts?
