The Underdog promo codeTOPACTION gives eligible new users two separate benefits before Giants vs. Rams on Monday Night Football. New customers can claim a free Keep Your Million entry plus a 50% first-deposit match worth up to $1,000 in bonus funds.
Giants vs. Rams kicks off at 8:15 p.m. ET on ESPN and ABC from SoFi Stadium. Jaxson Dart, Kyren Williams, Malik Nabers and Matthew Stafford all have player projections worth comparing against the Underdog lobby before submitting a Monday night NFL pick'em entry. Keep in mind, Underdog is one of the best alternatives to sports betting available today, along with various prediction markets.
The Giants enter Monday at 1-0 after beating Dallas, while Los Angeles is trying to respond to its Week 1 loss to San Francisco. Aaron Donald is expected back after two years away from the NFL, Myles Garrett is on injured reserve following knee surgery and Puka Nacua carries a questionable designation into the Rams' home opener.
Dart adds another angle after completing 23 of 29 passes for 230 yards and three touchdowns in Week 1 while adding 54 rushing yards. If New York spends more time playing from behind Monday, his passing and rushing volume could both rise.

Giants vs. Rams Picks on Underdog Tonight
Several current player-prop markets give us useful benchmarks for building an Underdog entry before Monday Night Football.
These are market reference points rather than confirmed Underdog projections. Compare each number against the live Underdog lobby before submitting a card, since Underdog can post different thresholds and adjust them throughout the day.
| Player | Current Market | Underdog DFS Pick |
|---|---|---|
| Jaxson Dart | 31.5 rushing yards | Higher at 31.5 or lower |
| Kyren Williams | 63.5 rushing yards | Higher at 63.5 or lower |
| Malik Nabers | 63.5 receiving yards | Higher at 63.5 or lower |
| Matthew Stafford | Around 244.5 passing yards | Higher around 244.5 or lower |
Jaxson Dart Higher Than 31.5 Rushing Yards
- Pick: Jaxson Dart higher than 31.5 rushing yards
Dart's rushing market sits around 31.5 yards entering Monday night after he ran 11 times for 54 yards against Dallas in Week 1.
The game script is the strongest reason to target the higher side. New York is a road underdog, which should create more obvious passing situations if Los Angeles builds a lead. Those downs also create scramble opportunities when the pocket breaks down or the Rams play tighter coverage downfield.
Garrett being unavailable takes one premier edge rusher out of the matchup, even with Donald returning to strengthen the interior.
If Underdog keeps Dart at 31.5 rushing yards or lower, the higher side is the preferred Giants projection.
Kyren Williams Higher Than 63.5 Rushing Yards
- Pick: Kyren Williams higher than 63.5 rushing yards
Williams' current rushing benchmark sits around 63.5 yards, and the expected game script works in his favor.
Los Angeles enters as the home favorite. If the Rams establish a lead, Williams should have opportunities to accumulate carries throughout the second half rather than depending on explosive runs to clear the number.
He remains the primary back in the Los Angeles offense despite Blake Corum also having a role.
At 63.5 rushing yards or lower in the Underdog lobby, Williams is the preferred Rams volume play.
Malik Nabers Higher Than 63.5 Receiving Yards
- Pick: Malik Nabers higher than 63.5 receiving yards
Nabers' current receiving benchmark is around 63.5 yards after he caught six passes for 69 yards in Week 1.
His role is the main selling point. Nabers remains the highest-upside target in the Giants passing game, and a negative game script could produce more attempts for Dart than New York needed against Dallas.
If the Giants fall behind, Nabers should have enough volume to challenge a receiving projection in the low 60s even if Los Angeles succeeds in limiting explosive plays.
Matthew Stafford Higher Than 244.5 Passing Yards
- Pick: Matthew Stafford higher than 244.5 passing yards if Puka Nacua is active
Stafford's current passing-yardage market is clustered in the low-to-mid 240s after an ugly opener in which he threw for only 155 yards with no touchdowns and an interception.
Monday gives him a chance to rebound at home, but Nacua's status matters considerably.
If Nacua is active without a reported snap limitation, Stafford has a much stronger path to clearing a number around 244.5. Los Angeles should also have better conditions offensively at SoFi than it did in its international opener.
If Nacua is ruled out or expected to be significantly limited, Stafford becomes the easiest leg to remove from the card.
Best Underdog Pick'em Picks for Giants vs. Rams
The strongest Monday Night Football entry starts with the projections that rely most on role and game script rather than uncertain injury news.
- Jaxson Dart: Higher than 31.5 rushing yards
- Kyren Williams: Higher than 63.5 rushing yards
- Malik Nabers: Higher than 63.5 receiving yards
- Matthew Stafford: Higher than 244.5 passing yards if Puka Nacua is active
Dart is the preferred Giants leg because a trailing game script can create more scrambling opportunities. Williams has the cleanest Rams volume case if Los Angeles plays from ahead.
Nabers fits the opposite side of that same script. More Giants passing attempts should create additional opportunities for New York's top receiver.
Stafford carries the most uncertainty because Nacua's final status directly affects the ceiling of the Rams passing game.
Conclusion
The Underdog promo code TOPACTION gives eligible new users a free Keep Your Million entry plus a 50% first-deposit match worth up to $1,000 in bonus funds, which is the highest offer among the top DFS sites.
For Giants vs. Rams, Jaxson Dart higher than 31.5 rushing yards is the preferred pick'em target if Underdog posts that number or lower.
Kyren Williams higher than 63.5 rushing yards and Malik Nabers higher than 63.5 receiving yards provide two additional volume-based options from opposite sides of the matchup.
Stafford's higher passing projection becomes more attractive if Nacua is cleared without a meaningful limitation.
Check the live Underdog lobby before the 8:15 p.m. ET kickoff because projections can move as injuries, inactives and entry volume change throughout Monday.
