SAN FRANCISCO – The San Francisco 49ers are heavy -550 moneyline favorites against the New York Giants on Thursday Night Football. New York has -110 odds to cover a 10.5-point spread without Saquon Barkley.

San Francisco’s dominant defense and dynamic offense makes them the clear legal sports betting favorite against the Giants.

San Francisco 49ers vs New York Giants Betting Lines

Team	Spread	Moneyline	Total
San Francisco 49ers	-10.5 (-110)	-550	O45.0 (-110)
New York Giants	+10.5 (-110)	+390	U45.0 (-110)

The 49ers were 9-1 against the spread as a home favorite in 2022. They were also 3-1 against the spread as 9.5-point or greater favorites.

San Francisco cruised to a 23-point victory in Week 1 and would have covered the 7.5-point spread in Week 2 if the Los Angeles Rams didn’t kick a field goal as time expired.

Meanwhile, the Giants failed to cover the spread at legal NFL betting sites in their first two games. New York needed their biggest comeback since 1949 to defeat the Arizona Cardinals after dropping Week 1 40-0 to the Dallas Cowboys.

The Giants are in no position to cover the 10.5-point spread, especially without Saquon Barkley. Many believe Barkley will miss three weeks with a sprained ankle.

An MRI showed that Giants’ RB Saquon Barkley suffered an “ordinary” ankle sprain that now is expected to sideline him three weeks, per source.

With such a large spread and short -550 moneyline odds for the 49ers, other betting value is available with Brock Purdy player props.

Brock Purdy Passing Props

The legal California sports betting sites have Purdy projected for 226.5 passing yards on Thursday night. He threw under 226.5 passing yards in both games this season.

Brock Purdy Passing Yards Prop

Over 226.5 Passing Yards -115
Under 226.5 Passing Yards -115

The 49ers dominated their way to victory in Week 1 and 2, making it unnecessary for Purdy to throw the ball later in the game. The under with -115 odds at legal NFL betting is the best bet with San Francisco heavily favored again for Thursday Night Football.
