Week 15 wraps up with a big one on Monday Night Football: the Pittsburgh Steelers hosting the Miami Dolphins. It's the kind of primetime clash that could shake up the AFC playoff picture.
The Steelers just came off a gritty 27-22 win in Baltimore on Sunday. That victory has them sitting pretty as the favorites to snag the AFC North crown. Under Mike Tomlin, this team's been solid at home, they've gone 2-1 against the spread when favored on their own turf this season. Pittsburgh's got that tough, never-quit defense and a run game that's kept them in every fight. Now they're back at Acrisure Stadium, where the crowd's always roaring, ready to make life miserable for any visitor.
Over in Miami, things are heating up too. The Dolphins just demolished the Jets 34-10 in a total blowout. That win marked their fourth straight victory and fifth out of their last six games. Mike McDaniel's squad is suddenly playing like a team that could make some noise in the playoffs. Their speed on offense is scary, especially with the great news on injuries. De’Von Achane looks good to go, which means Miami's backfield could be electric again. Achane's that spark plug who can turn a short pass or handoff into a house call, and having him healthy changes everything for their attack.
Pittsburgh got a boost too, with positive updates on D.K. Metcalf. Having their star receiver on the mend adds another weapon to an already dangerous lineup, making this matchup even juicier.
As we gear up for kickoff, here are my bold predictions for this Steelers-Dolphins Monday Night Football showdown in Week 15.
I’m on Steelers -3.5 and the Under 41.5 in this strange Monday night matchup. Even the market behavior here has been confusing. Miami opened catching more than a field goal, and instead of the number climbing toward Pittsburgh -4 as I expected, books have shaded the Dolphins with heavier juice or dipped toward -3. That doesn’t change my read. If I’m backing Pittsburgh, I want the flat -3, but I still think the Steelers are the right side.
Miami’s win streak looks good on paper, but the substance hasn’t matched the results. They’ve won four straight, yet three of those victories came against depleted opponents. Last week turned into a glorified scrimmage once New York was forced to play a quarterback making his NFL debut. Miami controlled the game on the ground and milked the clock, but they didn’t exactly prove they can move the ball consistently against a capable defense.
Pittsburgh, meanwhile, is coming off its most impressive performance of the season. The Steelers went into Baltimore and survived a game that easily could have flipped late, but that’s exactly where this defense thrives. Yes, the Ravens piled up yards, but much of that came when they were chasing the game. In the moments that mattered, Pittsburgh tightened up, holding Baltimore to just two red-zone scores on six trips. This "bend-but-don't-break" profile is backed up by the Steelers ranking 7th in the NFL in Red Zone Defense (TD conversion rate).
Weather pushes me even further toward Pittsburgh and the Under. Acrisure Stadium is expected to be brutally cold, with temperatures around 20 degrees. This is about as far removed from Miami conditions as possible, and it matters when Tua Tagovailoa is involved. His track record in cold-weather games speaks for itself: he is 0-7 SU in games when the temperature is 46 degrees or colder. This is the kind of environment where the Steelers’ pass rush can completely take over.
Miami’s offensive line remains a problem, ranking near the bottom of the league in both pass-block and run-block win rate. That’s a dangerous combination against a Pittsburgh defense that ranks top five in pressure rate and thrives on forcing mistakes. Tagovailoa’s efficiency collapses under pressure, and the Steelers lead the league in turning takeaways into points. Extra possessions for Pittsburgh swing this matchup decisively.
The Dolphins’ offense has leaned heavily on De’Von Achane and the run game to survive, pounding the run and shortening games. That approach naturally favors the Under, especially if conditions deteriorate.
On the other side, Pittsburgh is not built to explode offensively, ranking 27th in the NFL in Total Offense. They don’t need style points. They just need to win field position, capitalize on mistakes, and let the defense control the game.
Everything about this matchup points to a grind. Cold weather, conservative game plans, two offenses that struggle to generate chunk plays, and a Steelers defense that thrives at home in primetime. I see Pittsburgh doing just enough to pull away late in a game that never threatens the total. Give me the Steelers laying the points and the Under as my preferred angle.
