NFL parlay tonight - 49ers vs. Seahawks

After simulating tonight's game over 10,000 times, our model has identified the following projections and probabilities for the parlay picks that make up our three-leg same game parlay in 49ers vs. Seahawks on Saturday night, January 3.

Leg 1: Jaxon Smith-Njigba 90+ receiving yards

The first leg of our Niners-Seahawks parlay tasks Seattle's prolific WR Jaxon Smith-Njigba to tally at least 90 receiving yards for the 14th time this season.

JSN has hit this in all but three games during his campaign as the league's Offensive Player of the Year favorite and receiving yards leader. While two of those unders have come in his past five games, it's worth noting both were blowouts where he wasn't utilized in his usual field-stretching fashion (his only games without a catch of 25+ yards).

That's highly unlikely to be the case in this game where the winner will take NFC's No. 1 seed, so expect JSN to be featured heavily in his typical big play role, projecting for a hair under 100 receiving yards by the Dimers model.

The 49ers' defense has given up their share of big games - they just allowed receiving performances of 138 (Luther Burden III) and 94 (Colston Loveland) in their most recent game, as well as 115 and 185 yards to Trey McBride and Michael Wilson vs. the Cardinals a few weeks ago, while JSN put up 124 vs. the Niners way back in Week 1.

Leg 2: Jauan Jennings 40+ receiving yards

For the next leg, we're also going with a receiving line, albeit much lower on the 49ers' side of things.

Niners' WR Jauan Jennings hasn't emerged as an elite WR1, but has been a consistent part of this offense. In the second half of the season, he's recorded eight total TDs with 40+ yards and 6+ targets in six of his his past nine games.

His two games under this mark during that span saw him land on 39 and 37 yards with some bad luck; otherwise, he's been as reliable as it gets in the middle of the field.

Seattle's passing defense is very good, but it hasn't played many high-powered offenses lately. Meanwhile, they allowed three receivers to hit this mark in a shootout with the Rams in Week 16, (headlined by Puka Nacua's 225 yards).

Jennings is projected alongside Ricky Pearsall (questionable) as the Dimers model's leading WR for San Francisco in this game at 46.9 yards.

Leg 3: Christian McCaffrey anytime TD scorer

For the final leg of this same game parlay, we'll go with none other than RB Christian McCaffrey to score a touchdown.

CMC is our model's leading TD scorer probability in this game at a substantial 60.3%, giving us nearly fair odds at his -160 available.

McCaffrey's 17 touchdowns are tied for second-most in the NFL as he heads towards completing his Comeback Player of the Year campaign, and he'll be the 49ers' focal point of the offense as usual.

The Dimers model identifies big scoring upside for him in this game, with an edge to score 2+ touchdowns at +390 odds and a 23..6% TD probability. That's great standalone value as a straight bet, but for the sake of this parlay, we just need him to score once.

The 49ers get a 58.2% probability to cover the +2.5 spread and their most likely path to doing so is via CMC finding the end zone as their number one weapon.
