Week 4 of the NFL season has arrived, and seven undefeated teams remain.

As opposed to Weeks 2 and 3, there are very few lopsided betting lines this time around. The Los Angeles Chargers are the biggest favorite, owning a whopping 16.5-point spread in their road game against the Miami Dolphins. The only other double-digit line is in Los Angeles, where the Rams are 10-point favorites against the Tampa Bay Buccaneers.

The New England Patriots will face a division rival and fellow 3-0 squad in the Buffalo Bills as 7.5-point road favorites.

Here are the betting lines for Week 4, per Bovada:

Week 4 will kick off Thursday with the Green Bay Packers hosting the Philadelphia Eagles.
