NFL Week 6 betting lines: The Lions being favored in Dallas is the latest sign of the NFC's power shift

Less than a year ago, the Detroit Lions were 4.5-point underdogs for a Week 17 game on the road against the Dallas Cowboys.

Never mind, the Lions were a game better than Dallas at the time, and ultimately went much further than Dallas once the playoffs began. The Cowboys were favored at home, and they ultimately prevailed by a point to earn a tiebreak over Detroit in the NFC standings.

Fast forward to today, and the Lions are returning to Dallas, only this time they’re the favorites. And they’re laying a full field goal in the latest example of the changing of the guard that’s taken place at the top of the conference. Here’s a look at that game and every other line for Week 6, provided by BetMGM.
