Bad offensive line play can take this potentially Top 5 offense and reduce it to shambles. It’s been the most consistent source of concern for months, from the Doug Free episode to the failure to upgrade in free agency. Travis Frederick purports to be an asset to the run game, but this is still a passing team in a passing league; without quarterback protection, the Cowboys are dead where they stand. Defensively, it’s no different. Without effective pass rushers and run-stopping defensive tackles, and with glaring coverage concerns at safety, this secondary will have a long season.
