Pittsburgh Steelers vs Detroit Lions Game Preview and Analysis

Any time the Steelers and Lions share the schedule, memories of their quirky history resurface, including the infamous 1998 Thanksgiving coin toss and the 16-16 tie from November 2021. From a situational standpoint, this matchup carries far more urgency for Detroit than it does for Pittsburgh.

The Steelers are coming off a 28-15 home win over Miami on Monday night, which forces them into a short-week road spot. While Pittsburgh took care of business, the underlying performance was less convincing, as Miami averaged 5.9 yards per play and repeatedly moved the ball before stalling on key downs. With the AFC North likely coming down to Week 18, it is fair to question how much Pittsburgh empties the tank here.

Health also plays a role. TJ Watt suffered a collapsed lung during a dry needling treatment and, while hopeful to return later in the season, rushing him back here would make little sense. On the road, Pittsburgh has struggled to cover numbers, posting a 2-4 ATS mark away from home.

Detroit, meanwhile, is in a very different place. The Lions playoff margin for error is thin, and motivation should be high. Detroit has been reliable when laying big numbers, going 5-2 ATS as a favorite of six points or more. This is the type of game where effort, urgency, and game script align in the Lions favor.

  • PIT is 2-4 ATS on the road this season.
  • DET is 5-2 ATS as a favorite of six points or more.
  • The last two meetings between these teams failed to produce a winner outright.
  • Last time these two teams met, the game ended in a 16-16 tie in November 2021.
  • Miami averaged 5.9 yards per play against Pittsburgh last week, despite scoring only 15 points.

Key Injuries and Notes for PIT and DET

  • PIT: TJ Watt is dealing with a collapsed lung and is unlikely to be rushed back.
  • DET: No major injuries highlighted entering this matchup.

Detroit Lions 27, Pittsburgh Steelers 20
