Sample Pick'em Lineup for Thursday's Preseason Slate
Underdog runs on pick'em entries, where you take a player higher or lower on a statistical projection, which makes it distinct from sports betting. Here is a sample three-pick entry across both NFL Network games. Since preseason snaps shift right up to kickoff, so confirm the posted projections and player availability in the app before you lock anything in.
- Jordan Love, higher on passing yards (Packers vs. Steelers, 7 p.m. ET). Green Bay has said Love will play the opener, and a starter taking real first-team snaps clears a modest preseason line more easily than a rotation of backups.
- Mason Rudolph, higher on completions (Steelers vs. Packers, 7 p.m. ET). Pittsburgh's backup quarterbacks are lined up for extended run in Week 1, and volume is the whole game with a preseason passing prop.
- Will Levis, higher on passing yards (Titans vs. 49ers, 9 p.m. ET). Tennessee opened as the only road favorite on the slate, a sign the staff is treating this opener seriously, which points to more snaps for its veteran arms.
Why Underdog for the NFL Preseason Slate
Underdog is built for exactly this kind of night. Pick'em entries let you stitch players from both games into one card, so a quiet preseason score sheet still gives you something to sweat. The play $5, get $50 structure means your first entry unlocks ten times that in bonus entries, and you can spread them thin across the Packers, Steelers, Titans, and 49ers rather than load everything onto one game.
Preseason is a projection puzzle more than a talent contest, so lean into volume and confirmed playing time over big names, and let the bonus entries cover the variance. Once you determine the predictions you want to make, sign up with the Underdog promo code TOPACTION and claim a $50 bonus offer today to make your NFL picks.
