Poor tackling highlighted perhaps the Steelers' worst defensive performance in the last few weeks, but that is at least explainable due to the fact the Steelers had the very bottom of their secondary depth chart covering the high-production receivers of the Dallas Cowboys.
There is no explanation, though, for the execution and decision-making of Steelers receiver Antonio Brown.
His fumble on a punt return set up Dallas' game-tying touchdown, and a decision to not catch a punt pushed the Steelers 19 yards back with under three minutes to play in a tie game.
Brown's fumble came at 10:03 of the fourth quarter, right after the Steelers forced a punt, holding onto a 24-17 lead. The Cowboys took it as a reason to hang another long drive on the struggling Steelers defense. After holding on first and second down at the goal line, DeMarco Murray scored on a zone run, cutting back to the left.
