Offense can be Potent against terrible defensive teams like Giants, Raiders, Jets. Did tie against GB so I'll give them that.
Against the good teams? Bears, Eagles, Denver - offense was underwhelming to downright bad. Eagles, they started off fast, 2 TDs in first 2 drives then went into a shell. Also a common theme of these games is being on the road. This offense doesn't travel well, especially when that venue is outside a comfortable dome environment, which all of those teams had.
This has been a theme for a very long time.
The Arizona Cardinals game was a game that will most likely do them in. Arizona was on a 5 game losing streak going into that game and have been blown out both games since their win against us. Not only did they beat us, they dominated us. Score looked a little closer but Arizona's offense exerted their will, with Jacoby Brissett in our stadium. Offense was junk, defense couldn't get any stops. If they had won that game, they'd still have a fighting chance coming into the teeth of their schedule. They are now going to need to win some games against better teams and do it consistently. Trust them to do that? I don't.
