Rams vs Broncos Prop Predictions: SNF Player Props For 9/27/2026

Rams vs Broncos Full Game Pricing
Updated September 24, 2026
Los Angeles enters Sunday night at 1-1 after a 28-6 win over the Giants, while Denver is also 1-1 after holding Jacksonville to 13 points. The full-game Polymarket price gives the Rams a slight advantage, pricing Los Angeles at 56¢ to win and Denver at 44¢. The player prop market offers a more interesting angle, as two playoff contenders try to prove themselves in the Mile High City on Sunday Night Football.
A 5% Edge With Williams
Polymarket currently lists Williams over 49.5 rushing yards at 50¢, creating an implied probability of 50%. My projection places his probability of reaching 50 rushing yards at 55%, producing a 5% edge at the current price. I would consider the prediction playable through 54¢. That still leaves a 1% difference between my projection and the market price.
Price Discovery Advantage
Williams' rushing-yard ladder also deserves attention. Several thresholds are sitting close to 50¢ on Polymarket rather than displaying a smooth decline in probability as the required yardage rises. That suggests price discovery in these player markets is still thin. The 49.5-yard line stands out because Williams has already reached 85 yards on 12 carries against New York and is averaging 63 rushing yards per game despite sharing work with Corum.

Why Our Model Sees Value:
“Williams is averaging 5.48 yards per carry through two games, while Denver has allowed 5.1 yards per carry through its first two contests. Los Angeles also owns one of the NFL’s strongest early groups in terms of rushing efficiency.”
The Rams have been one of the NFL’s most efficient rushing teams through two games. And Denver is last in EPA allowed per carry and 24th in opponent rushing success rate, with opponents averaging 5.1 yards per attempt. Los Angeles, meanwhile, has averaged roughly 5 yards per carry and graded near the top of the league in adjusted line yards.
That combination gives Williams room to clear 49.5 without requiring a huge workload. At 4.5 yards per carry, 12 attempts would produce 54 yards. Williams had 12 carries for 85 yards against the Giants after recording 11 attempts in the opener, so the required volume is consistent with his current role.
The strongest argument against this prediction is Los Angeles’ increasingly balanced backfield. Corum matched Williams with 12 carries against New York and turned them into 79 yards. Williams played well, but the Rams had no need to force a traditional lead-back workload onto one player. That makes a projection near 20 carries unrealistic based on the first two weeks.
The 49.5-yard requirement for this prop helps offset that concern. Williams does not need to reclaim a dominant carry share. He needs roughly 11 to 13 productive attempts, a range he has already occupied in both games this season. LA's ability to use multiple backs has our Rams vs Broncos prediction for the full game focused on the under, while Williams should be able to reach this total.
Denver’s defense was much better against Jacksonville than it was in Week 1. The Broncos allowed 95 rushing yards on 24 attempts after surrendering 220 rushing yards on 38 attempts against Kansas City in the opener. Jacksonville still found some individual efficiency, with Bhayshul Tuten gaining 65 yards on 13 carries.
Denver has been considerably stronger against the pass in the early efficiency rankings, which gives Los Angeles another reason to stay patient with the ground game. The current Polymarket game price also has the Rams slightly favored, a setup that supports the possibility of steady rushing volume rather than a game in which Williams is pushed out of the gameplan by an early deficit.
Puka Nacua did not practice Wednesday after missing the Giants game with hip and groin issues, although his status for Sunday has not been finalized. Jordan Whittington and Colby Parkinson also missed Wednesday’s practice. If the Rams remain short-handed in the receiving group, Sean McVay has another reason to lean on the running backs and shorter, lower-variance offense.
Williams’ reduced share makes higher rushing thresholds less appealing, but 49.5 sits low enough to account for the committee. At 50¢, the current Polymarket price does not fully reflect the quality of the rushing matchup or Williams’ efficiency through two weeks, making the over the strongest player-market prediction in this matchup.
