Line gates currently set the 49ers as ~-2.5 favorites at MetLife, with the Over/Under floating in the 48 to 48.5 range depending on sportsbook. Consensus has tilted toward the Over recent days as bettors react to both teams’ recent high-scoring trends and defensive vulnerabilities. Public money appears slim but competent: sharp bettors respect San Francisco’s overall roster depth, especially their offensive weapons when healthy. Steam action has nudged line movement slightly toward Niners, particularly after their underwhelming showing vs. Houston that revealed more fissures than fear. Giants bettors may appeal for value here given the injuries affecting both sides. Key prop bets to monitor include passing yard lines for Mac Jones (especially if Purdy is inactive) and receiving yards for Jennings, possibly exploitable against Green or Banks. The key to watching this market will be how drastically the injury news drops out close to kickoff—if Purdy is ruled out and Giants’ corners remain down, expect line or total shifts, but nothing dramatic unless another starter is added to the injury report.
