Six NFL teams are still undefeated in the 2015 season, and the five that are playing on the Week 5 schedule are favored to win their upcoming games. The Green Bay Packers, Atlanta Falcons, New England Patriots and Denver Broncos are among the biggest favorites of the week, while the Cincinnati Bengals are favored against the defending NFC champs.

After winning their fourth straight game to start the season, the Packers are tied with the Kansas City Chiefs as the biggest favorites of the week. The Packers are giving 9.5 points to the St. Louis Rams, who upset the undefeated Arizona Cardinals in Week 4. Even with a 1-3 record, the Chiefs are 9.5-point favorites when they host the Chicago Bears, who got their first win of the season in Week 4 when Jay Cutler returned from injury.

The Patriots have two weeks to prepare for the Dallas Cowboys, whom they are giving 8.5 points on Sunday. The Cowboys went 2-0 with Tony Romo as their starter, but have lost two straight games with Brandon Weeden at quarterback.

After upsetting the Philadelphia Eagles last week, the Washington Redskins are getting more than a touchdown in their visit to Atlanta. The Falcons had the biggest win in Week 4, defeating the Houston Texans by 27 points.

The Denver Broncos are significant road favorites in their visit to Oakland. Denver’s plus-28 point differential is the lowest of any unbeaten team.

The Bengals are the weakest favorites of Week 5, giving the Seattle Seahawks 1.5 points in Cincinnati. The Seahawks are 0-2 on the road this year.

There are still no betting odds for the Thursday night game between the Indianapolis Colts and Houston Texans because it’s unknown if Andrew Luck will play. The Colts went from nine-point favorites to four-point favorites last week when it was announced that Luck was out with a shoulder injury.

The New York Jets, Miami Dolphins, Carolina Panthers and Minnesota Vikings all have byes in Week 5.
