It's the star skill position players who come to mind first when thinking about this Cowboys-Dolphins marquee matchup. Those players are healthy with the exception of Tyreek Hill, who I do expect to play after he missed last week because of an ankle injury.

But it's injuries on the offensive lines and the underrated defenses that command my attention making me like the Under here.

The Cowboys' secondary ranks second-best in the league in road games, holding quarterbacks to 150.9 net passing yards. Micah Parsons has 12 1/2 sacks. I rank him as one of the three best pass rushers in the NFL. Right tackle Austin Jackson is going to be lined up against Parsons. Jackson is dealing with an oblique injury. While I expect Jackson to play, the Dolphins will be without center Connor Williams and two other starters, Robert Hunt and Isaiah Wynn. Tua Tagovailoa is not a mobile quarterback.

Miami's defense has come on. It's much improved and Dallas has its own offensive line injuries. Star left tackle Tyron Smith is out. Pro Football Focus ranks Smith as the NFL's third-best offensive tackle. All-Pro right guard Zack Martin is questionable with a quad injury. Bradley Chubb is having a dominant pass rushing season for the Dolphins. He's forced a league-best six fumbles and has 9 1/2 sacks.

Dak Prescott has played much worse on the road. His home/road split is 304 passing yards with a 122.5 quarterback rating and a 20-to-2 touchdown-to-interception ratio at home compared to 216 yards passing per game, an 84.2 passer rating and an eight-to-five touchdown-to-interception ratio on the road.
