Steelers vs Colts Pick, Prediction

Action Network NFL betting expert Brandon Anderson offers this prediction:

Pittsburgh just lost to Arizona and New England and barely even looked competitive. The Steelers looked like a playoff team two weeks ago and now feel dead in the water, the absolute last team you'd want to invest in. And that's exactly when the time is right to put your money on Mike Tomlin's guys.

This is a classic "Rah Rah" Tomlin spot. From Week 5 forward, Tomlin is 44-19-1 ATS (70%) as an underdog and won 37 of those covers straight up, an awesome 47% ROI for bettors on the moneyline. That trend is even better as an underdog coming off a loss, where Tomlin is 17-6 ATS and has won 16 of those 17 covers straight up, an 82% ROI on the moneyline.

Pittsburgh has run the ball well and stopped the run, and that's the right matchup against the Colts. It probably won't be pretty, but Rah Rah all the way. If you can wait to bet it live, because of Pittsburgh's poor starts, you might be able to get a better number sometime in the first half.

Pick: Steelers ML (+110)
