I stopped listening when he said "Dallas has a top 3 offensive line". This completely ignores the injury to Collins, the loss of Frederick, and the play on the field. Clearly the Cowboys do not have a top 3 offensive line anymore. So when you say, there is something wrong with the cowboys offense, it has to start with the most obvious problem. What Cowherd does is create a straw man to attack a point he cannot substantiate with facts. This is why he is wrong most of the time.
Watching the Rams game, what was wrong with the Cowboys offense? The OL was clearly a huge problem. Every play, game plan, scheme etc. starts with the premise that your guys block their guys. Xs and Os. If the OL does not get it done, nothing else drawn up on paper matters.
