New England Patriots at Indianapolis Colts

Although I’m not backing the underdog, the favorite is actually undervalued. The Colts are allowing the fifth-lowest expected points added (EPA) per carry while Patriots tally the second-highest rushing percentage. That correlates to their positive game scripts, but we’ve yet to see Mac Jones face a two-score deficit or more during their winning streak.

  • EPA is calculated by expected points scored based on the down, distance, and field position at the start of a play — juxtaposed with the play’s conclusion.

These teams were neck-and-neck in my power rankings this go-around, and there’s value with Indianapolis here.

Week 15 NFL Underdogs Angle: Pass, but consider Colts -2.5 or better
Best Available Odds: Colts

Tennessee Titans at Pittsburgh Steelers

Over the Titans’ last four games — all without running back Derrick Henry  — they’re generating the 10th-fewest EPA per play. Expect that regression to continue, as the Steelers should at least stay within a touchdown. If their defense is relatively healthy, they’re worth an ATS bet too.

Week 15 NFL Underdogs Angle: Consider Steelers ATS and teaser leg (+7 or better)
Best Available Odds: Steelers

Seattle Seahawks at Los Angeles Rams

As you’ll find in our NFL COVID-19 report, the Rams are affected on both sides of the ball. Does that mean the Seahawks win straight-up? Probably not, but Russell Wilson will have success versus this secondary minus Jalen Ramsey.

Week 15 NFL Underdogs Angle: Consider Seahawks teaser leg (+10.5 or better)
Best Available Odds: Seahawks

  • Update: This game has reportedly been postponed until Tuesday, voiding teaser bets at most sportsbooks.

New Orleans Saints at Tampa Bay Buccaneers

Surprisingly, the Buccaneers have struggled most against opposing ground games since their Week 9 bye, allowing the most EPA per carry. Not only has Sean Payton’s bunch has racked up the fourth-highest rushing percentage, but his defense has continually given Tom Brady fits like we saw in the Saints’ Week 8 upset win. Two scores is too many for New Orleans.
