Or in Dak's case - he goes 6 straight 3 and outs to start a game. In the meantime the defense gets worn down by half and is getting their butts kicked and Dallas trails 28-0. The opposing team takes their foot off the gas and Dak is only then able to start moving the ball at will and his homers are fooled into thinking he is leading a massive come back. In reality, the opposing defense is letting them start piling up yards.
Any yards gained in this example are 'garbage time'.
I understand why some want to defend Dak, but there are far too many instances where the defense started getting their rear ends handed to them because the offense stunk and kept their own defense on the field too long. The offense has to do their part too.
