Underdog's DFS product works differently from a sportsbook or prediction markets. Instead of betting LSU -2.5 or buying an outright winner contract, users build pick'em entries by selecting higher or lower on the player and team projections available in the app.
The welcome offer from the Action NetworkUnderdog bonus code TOPACTION adds a 50% match to the first qualifying deposit, up to $1,000 in bonus funds. A $100 deposit earns a $50 match, while a $2,000 deposit reaches the full $1,000 promotional maximum.
Keep Your Million is a separate promotion from the deposit match. Eligible users can opt into the contest for free and receive an entry into Underdog's $1 million pick'em pool. From there, the goal is to build the qualifying entry required by the contest and stay alive as the competition progresses.
That means new users can take advantage of both promotions without one being dependent on the other. The deposit triggers the 50% bonus-funds match, while opting into Keep Your Million provides the separate contest entry.

LSU vs. Ole Miss Preview and Underdog Picks
The biggest variable entering Saturday is LSU quarterback Sam Leavitt, who was listed as doubtful with a throwing-shoulder issue. That makes his final status worth checking before building an Underdog entry around any LSU quarterback projection.
| Player | Underdog Lean | Number to Target |
|---|---|---|
| Sam Leavitt | Wait for final status | 38.5 rushing yards |
| Trinidad Chambliss | Higher passing yards | 277.5 passing yards |
| Kewan Lacy | Lower receiving yards | 16.5 receiving yards |
- Sam Leavitt: Leavitt still carries plenty of rushing upside when healthy, with the current rushing market sitting around 38.5 yards. The problem is availability. With Leavitt listed doubtful, there is little reason to lock in a higher-or-lower position before LSU confirms whether he will play. If Leavitt is cleared and Underdog posts him around 38.5 rushing yards, his dual-threat role makes that number worth revisiting. If he sits, LSU's offensive distribution changes enough that the rest of the Tigers' projections should be reassessed as well.
- Trinidad Chambliss: Higher than 277.5 passing yards. Chambliss has thrown for 561 yards through Ole Miss' first two games, and the current passing-yard market sits at 277.5. Action Network's projection is even higher at 292.82 yards, giving the Higher side some support if Underdog posts a similar number. LSU's defense is the toughest matchup he has seen this season, but Ole Miss may need Chambliss to carry more of the offense if the Tigers slow down the running game. That gives his passing volume a path to clearing the high-270s.
- Kewan Lacy: Lower than 16.5 receiving yards. Lacy's rushing workload remains secure, but the receiving market offers a cleaner angle. His current receiving-yard line sits at 16.5, while Action Network projects him for 13.89 yards. Lacy has caught only two passes for nine yards through two games, and LSU's ability to control the line of scrimmage could make Ole Miss rely more heavily on Chambliss and its receivers rather than manufacturing extra targets for Lacy.
The best approach is still to check Underdog's live board before submitting an entry. If the app moves materially away from Chambliss 277.5 passing yards or Lacy 16.5 receiving yards, the value changes with it.
Why Lane Kiffin's Return is Key
Saturday is Kiffin's first trip back to Oxford since leaving Ole Miss for LSU.
Ole Miss promoted former defensive coordinator Pete Golding, who brings a 2-0 Rebels team into the first top-10 LSU-Ole Miss matchup since 1962. ESPN's College GameDay will also be in Oxford for the matchup.
Kiffin knows many of the players and concepts on the other sideline, while Ole Miss has firsthand familiarity with the offense he helped build before leaving.
That history adds another layer to the matchup, but it does not change the DFS approach. Leavitt's availability and the actual player projections posted by Underdog matter more than the storyline when deciding which higher-or-lower positions to use.
