Zach Charbonnet Over 41.5 rushing yards (-114)

Projection: 53.48 yards

Both he and his backfield mate, Kenneth Walker, have positive projections, but there's more value in Charbonnet going Over his yardage line.

Jaxon Smith-Njigba Over 94.5 receiving yards (-114)

Brock Purdy Over 242.5 passing yards (-114)

Projection: 254.55 yards

San Fran's QB averaged nearly 300 yards per game in December, while we don't project him that high, we do think he finishes beyond a much lower total.

Bet Purdy passing yards now at FanDuel!

Christian McCaffrey Over 67.5 rushing yards (-114)

Projection: 67.81 yards

Our projections put CMC basically right at his posted total, which he's gone Over in five of his last six games.

Ricky Pearsall Over 43.5 receiving yards (-114)

Projection: 53.77 yards

Pearsall has 181 yards in his last two games, and we expect him to at least go Over a relatively low yardage line tonight.

Alternate-total bet
50+ yards (+120) - This prop shows strong value.

George Kittle Over 61.5 receiving yards (-114)

Projection: 65.02 yards

The star TE has finished the year strong, topping this number in his last six games, and we're forecasting him to go Over his total again in this matchup.
