Underdog Fantasy Promo Code TOPACTION: Submit $5 Lineup for Cardinals vs. Cowboys
Now that you've claimed the Underdog Fantasy promo code TOPACTION, it's time to submit your first lineup. Select any player projection from the Cardinals vs. Cowboys game on Monday Night Football and choose "Higher" or "Lower." As you add more picks, you can potentially earn a larger payout.
In my example below, I have a three-pick lineup, so I must choose between the Standard and Flex options. With the Standard lineup, I get a 6x payout if every pick wins. The Flex entry offers a 3x payout with a perfect lineup, or I get my stake back with a 2-for-3 lineup.
Keep reading to learn why I'm using these NFL picks in my Underdog lineup.
| Player | Team | Pick |
|---|---|---|
| Dak Prescott | Dallas Cowboys | Lower Than 273.5 Passing Yards |
| Bam Knight | Arizona Cardinals | Lower Than 12.5 Longest Rush |
| Budda Baker | Arizona Cardinals | Lower Than 7.5 Tackles + Assists |
Dak Prescott is having a strong season, leading an explosive Cowboys offense. However, it may surprise some to know that Prescott hasn't surpassed 265 passing yards in four consecutive games. Overall, he's recorded fewer than 273.5 passing yards in six out of eight games this season. In my opinion, the Cowboys don't need a big passing night to defeat the Cardinals.
The Cardinals' running back situation has been a revolving door, with Bam Knight now getting the start in tonight's game. Although Knight has been involved this season, we haven't seen any explosive runs from him. His longest rush of the season is just 10 yards, and I'm skeptical about him achieving a 13+ yard carry on Monday Night Football.
Turning to the defensive side, Cardinals safety Budda Baker started the season strong with 18 tackles and assists over the first two games. However, since then, he has only surpassed eight total tackles once. I'm expecting him to have another game with seven tackles or fewer.
