Giants vs. Rams Prediction and Why I Like It
The Giants arrive off a 28-20 win over Dallas. The Rams limped home from Melbourne after a 27-7 loss to San Francisco. Aaron Donald returns tonight on a snap count at SoFi Stadium, but Myles Garrett is on IR for this game and the following three weeks, at least.
| Market | Number |
|---|---|
| Spread | Rams -6.5 |
| Total | 47.5 |
| Records | Giants 1-0, Rams 0-1 |
My Giants vs. Rams prediction: Rams win by over 6.5 points NO (48%) and over 47.5 total points NO (50%).
Three reasons drive my Giants vs. Rams prediction this evening:
- Los Angeles leaned on three tight end personnel at a 38% clip in Week 1 and produced almost no explosive plays. This is the offense Sean McVay wants to run, but there are questions over how efficient it is.
- Puka Nacua enters this game as a game-time decision while nursing a hip injury, and Matthew Stafford would suffer greatly tonight without his star wide reciever.
- Both teams want to rush the ball with star NFL running backs Kyren Williams and Cam Skattebo, which translates to grinding clock, fewer possessions, and less points.
Why Trade Monday Night Football With Polymarket Referral Code ACTION?
