NFL 2025-26: Week 15 Monday Preview & Betting Tips

December 13th 2025, 11:11am, By: Andy Rosos

NFL Week 15 Monday Betting Tips

Week 15 lands at the sharp end of the regular season, where contenders are thinking about seeding and pretenders are fighting to keep the door ajar. This Monday morning slate blends cross conference tests with NFC heavyweights clashing in games that feel like playoff rehearsals. Execution, health, and late season composure will matter more than ever.

NFL Week 15 Monday Betting Tips

Green Bay Packers at Denver Broncos

8.25am (AEDT)

Denver return home with confidence built on discipline and defensive toughness. The Broncos have leaned into a physical identity at altitude, using crowd noise and pass rush to disrupt timing and force mistakes. Bo Nix has continued to grow week by week, managing games well and making smart decisions on third down, while the run game has allowed Denver to control tempo and avoid putting the offence in obvious passing situations. At home, they have been comfortable turning games into grind-it-out contests that suit their strengths.

Green Bay arrive as a dangerous but still inconsistent opponent. Jordan Love has taken clear steps forward this season and the Packers offence has shown it can move the ball efficiently when protection holds. Their run game has helped balance things out, but road performances have been mixed, particularly against teams that can generate pressure without blitzing. Defensively, Green Bay have competed hard, though they have struggled at times to get off the field late in halves.

Prediction: This feels like a game Denver can shape on their terms. The altitude, defensive pressure, and willingness to slow the pace should test Green Bay’s composure for four quarters. The Packers will land a few punches, but I trust the Broncos ability to control field position and close late at home. I like Denver to win 23 to 19 in a physical, lower scoring contest.

Detroit Lions at Los Angeles Rams

8.25am (AEDT)

Los Angeles come home looking every bit like a team built for January football. Their offence continues to hum behind sharp quarterback play and creative play calling that stretches defences horizontally and vertically. The Rams have also found consistency on defence, tightening up in key moments and doing enough to protect leads. At home, they tend to play with confidence and clarity.

Detroit arrive as a genuine NFC playoffs contender with minimal fear of the moment. Their offence has been one of the more balanced in football, capable of controlling games on the ground or pushing the ball when needed. The Lions defence has stepped up in big spots this season, particularly against the run, and they have shown an ability to match physicality with anyone. This is not a team looking for validation, they expect to win these games.

Prediction: This feels like a playoff preview. Both sides will trade momentum, but the Rams home advantage and ability to generate explosive plays late give them the edge. Detroit will not go quietly, yet Los Angeles ability to finish drives at home should be decisive. Rams win 27 to 24 in a high quality contest.

Minnesota Vikings at Dallas Cowboys

12.20pm (AEDT)

Dallas return home with plenty at stake and an offence that tends to look far more dangerous indoors. Dak Prescott has generally thrived in these environments and the Cowboys passing game can put pressure on opponents quickly when rhythm is established. Defensively, Dallas have been inconsistent but their pass rush at home often finds another level, especially in must win spots.

Minnesota arrive still searching for consistency as the season winds down. They have shown flashes offensively but have struggled to string together complete performances, particularly on the road. Young quarterback play has brought both excitement and volatility, and the defence has had trouble holding up when games speed up. The Vikings can compete early, but sustaining that level for four quarters has been a challenge.

Prediction: Dallas should be able to dictate this matchup if they protect the ball and avoid self inflicted mistakes. Minnesota will have moments, but the Cowboys offensive upside and home conditions favour them. I like Dallas to win 28 to 20, pulling away late as the Vikings struggle to keep pace.
