The NFL preseason is mainly for these players to get some additional practice. And you can do the same on Underdog. Use this time to become familiar with the different features and types of entries.
For example, you can make a standard entry by making 2+ picks. All must hit to receive a payout, but these result in the most winnings. The other option is to flex an entry of 3+ picks and still receive a smaller payout if only one leg is incorrect. These are just some of the popular Higher/Lower markets you can find for the NFL preseason games on Thursday:
- Joe Burrow: 68.5 passing yards
- Ja’Marr Chase: 24.5 receiving yards
- Anthony Richardson: 0.5 passing TDs
- Cooper Rush: 118.5 passing yards
- Brock Bowers: 0.5 rush + receiving TDs
- Ashton Jeanty: 23.5 rushing yards
- Jalen Milroe: 98.5 passing yards
