Since joining Buffalo in 2018, Josh Allen and the Bills are 12-2 straight-up versus the Dolphins. That makes outright Week 9 NFL bets for Bills vs. Dolphins (+6.5) on Sunday pretty decisive, but Buffalo is only 7-6-1 against the spread over this stretch. So, you'd be forgiven if you want to avoid inserting ATS NFL bets from this game into a Week 9 NFL parlay, but which other predictions should you consider? Other divisional matchups on the Week 9 NFL schedule include Saints vs. Panthers (+7), Giants vs. Commanders (-3.5), Lions vs. Packers (+3.5) and Rams vs. Seahawks (+1.5).

We can tell you Hartstein loves the Chargers (-1.5, 42.5) to cover on the road versus Cleveland. "Justin Herbert has averaged nearly 9 yards per attempt the past two games, with rookie Ladd McConkey erupting and soon to be joined by wideouts returning from injury. Lay the small number," Hartstein told SportsLine.

Hartstein also has locked in two other confident Week 9 bets, including backing a SHOCKING road team whose opponent's play at home "has been a disaster!" You ABSOLUTELY need to see his picks before betting on NFL Week 9.
