Our offense shrinks against good teams. Tua seems to have a cap but Tyreek and others don't play very well either. We aren't tough enough to compete against good physical teams and without threat of a passing game our running game is non existent.
What confuses me is that they got it done against Dallas (granted Dallas isn't as good as Baltimore or Buffalo). And with the exception of Tennessee they took care of business against lesser teams, beating them easily, even with injuries. It makes it very frustrating.
