It’s hard to win football games at any level without winning the battle in the trenches. The Dallas Cowboys were reminded of that in Week 15 when the Buffalo Bills stampeded their way to a 31-10 rout of America’s Team. Dallas surrendered 266 rushing yards in the loss, calling into question its standing against the best teams in the NFC—and their run-heavy offenses.

The Cowboys were without nose tackle Johnathan Hankins on Sunday, and the defensive line suffered for it. The entire defense was bullied for four quarters. With the playoff-bound Miami Dolphins and Detroit Lions around the corner, fixing the run defense is imperative.
