My best bet for the Seahawks vs. Cardinals TNF game showcases how this strategy works. For tonight, I like for Sam Darnold to get 150+ yards (-900). Let’s look at the two possible outcomes when you wager $5 on these NFL odds.
- If Darnold throws for 150+ yards, you get $0.56 in winnings. The sign-up bonus also banks $300 in bonus bets.
- If Darnold fails to throw for 150+ yards, you don’t get any profit. Your $5 stake disappears, and you get no bonus bets.
