This matchup between the Lions and Packers sets up as a pivotal game for both teams, and with so much on the line, expect a more conservative approach from both sides. Defense will likely take center stage, as the Lions boast the league's third-ranked defense, allowing just 16.9 points per game, while the Packers rank 10th, giving up only 20 points per game.

Recent trends further support a lower-scoring outcome. In their last meeting, these teams combined for just 38 points, and the Under has hit in four of the Packers' last six games. The Lions have only exceeded 51.5 total points once in their last five games, and the Packers have seen just one game go over that number in their last six outings.

Historically, this rivalry has leaned toward defensive battles, with four of their last five meetings producing fewer than 51 total points. Both teams also hold identical 5-6-1 records on the over/under this season, highlighting their tendency for lower-scoring affairs.

With playoff implications on the line and both teams prioritizing defense and minimizing mistakes, this game has all the makings of a tightly contested, low-scoring battle. The Under 51.5 is a strong play.
