NFL Week 18 Preview: Odds, Spreads, Picks

It's hard to find an NFL rivalry that means more to fans than the Chicago Bears vs. Green Bay Packers. 

And it's hard to find a recent matchup between these seemingly ancient rivals that means as much as this Sunday's edition. 

The Packers need this win to quality for the NFC playoffs in Jordan Love's first season as starter. The Bears are out of playoff contention, but there's other franchise decision potentially hinging on the outcome of this finale. Such as: 

Will Matt Eberflus return as head coach? 

Will Justin Fields remain the team's starter next season?

Or does Chicago take a quarterback with the first overall pick in the 2024 NFL Draft?  

The Bears have not beaten the Packers since 2018 (yes, a real factoid), including a humbling 38-20 loss in Week 1 of the 2023 NFL season. However, that Bears have drastically improved in the last quarter of the season, going 4-1 in their last five games. 

Likewise, the Packers have surged after starting their season 2-4. Love (93.8 passer rating) has been electric in recent weeks and looks like the team's newest answer at quarterback for the next decade. 

On Sunday Night Football, Josh Allen and the surging Bills take on the Miami Dolphins. The Bills face a wide array of outcomes from this game: If they win, they are the No. 2 seed in the AFC; if they lose, they could miss the playoffs altogether.
