Build your first Underdog entry with two to eight picks. Then, choose whether each player goes “Higher” or “Lower” than the provided statistical projection. Each additional pick beyond the first two raises your potential payout multiplier.
Below are three of my favorite NFL picks for Sunday. Sign up with the Underdog promo code LABSNEWS, then use these picks, or any others you prefer, to craft your lineup.
- Shedeur Sanders to get “Lower” than 163.5 passing yards
- Jaxon Smith-Njigba to get “Higher” than 95.5 receiving yards
- Drake Maye to get “Higher” than 245.5 passing yards
After you make your player picks, choose how you want to finalize your NFL entry. A Standard Entry offers the higher payout multiplier but requires every pick to hit. A Flex Entry provides a safety net. This entry type lets you cash even with one miss. However, it comes with a lower payout multiplier due to the reduced risk.
For instance, a three-pick Standard Entry pays 6x the amount you put down if all selections hit. Submit those same picks as a Flex lineup, and your payout becomes 3x or 1x. The payout on a Flex entry is dependent on how many players clear their projections.
