Wrap up NFL Week 16 by building an Underdog lineup around your top pick options from the 49ers vs. Colts MNF matchup. Choose between two and eight picks, then decide whether each player finishes “Higher” or “Lower” than their listed statistical projection. Adding more picks increases your payout multiplier and overall upside.
Below is a sample Underdog lineup featuring 49ers vs. Colts MNF picks. Once you register with the Underdog promo code LABSNEWS, you can follow this example or create a fully custom entry to chase a payout on one of the top DFS sites available.
- George Kittle to get “Higher” than 66.5 receiving yards (NFL)
- Christian McCaffrey to get “Lower” than 60.5 rushing yards (NFL)
- Philip Rivers to get “Higher” than 160.5 passing yards (NFL)
After finalizing your picks with the Underdog Fantasy promo code LABSNEWS, select your entry type. Standard Entries maximize payout potential but require every pick to hit. Flex Entries provide a safety net, allowing one incorrect pick without losing the entire entry, though the payout is smaller.
As an example, a three-pick Standard Entry returns 6x your wager if it goes perfect. Submit those same picks as a Flex Entry, and the payout adjusts to 3x—or 1x if not all selections hit.
