Savvy bettors could jump on the Chargers with their Week 10 NFL picks, especially since Los Angeles is a perfect 4-0 against the spread on the road. They include the Packers (+5) against the Cowboys and the Chargers (+7) visiting the 49ers. That is the highest percentage through nine weeks since 1999, and there are eight such dogs this week, according to the NFL odds and NFL spreads from Caesars Sportsbook. NFL underdogs of four-plus points have fared well versus the spread entering the Week 10 NFL schedule, covering in 65% of their games.
