The slate wraps up with Raiders vs. Cardinals at 10 p.m. ET in Arizona. With a mix of starters, backups and roster longshots playing in each game, it will be necessary to look deep into the NFL DFS player pool when building preseason NFL DFS lineups.

Top NFL preseason DFS picks for Saturday

One of Kaylor's top DFS picks for Saturday is Dolphins quarterback Tua Tagovailoa. The former Alabama star was selected fifth overall in the 2020 NFL Draft. Known for his accuracy and quick release, he helped turn Miami into one of the league's top offenses in 2023. Despite early-career injuries, Tagovailoa has established himself as one of the top young quarterbacks in the NFL as the Dolphins face the Jaguars at 7 p.m. ET.

Tagovailoa has thrown for over 14,000 yards and more than 80 touchdowns since entering the NFL in 2020. He led the league in passer rating (105.5) in 2022 and helped guide the Miami Dolphins to back-to-back playoff appearances in 2022 and 2023. A Pro Bowl selection in 2023, Tagovailoa has become one of the NFL's most efficient passers when healthy.

Part of Kaylor's NFL DFS strategy includes rostering Seahawks wide receiver Jaxon Smith-Njigba. The former Ohio State star was the No. 20 overall pick in the 2023 NFL Draft. He set the Rose Bowl record with 347 receiving yards in 2022, showcasing his elite route-running and playmaking ability. In his rookie NFL season, Smith-Njigba quickly carved out a role as a reliable slot receiver alongside DK Metcalf and Tyler Lockett.

With Metcalf and Lockett no longer with Seattle, Smith-Njigba is now in line to become the No. 1 option in the Seahawks' passing attack. In two NFL seasons, he has accumulated 163 receptions for 1,758 receiving yards and 10 total touchdowns. In his breakout 2024 campaign, he caught 100 passes for 1,130 yards with six touchdowns and earned his first Pro Bowl selection. Seattle will visit Green Bay at 4 p.m. ET on Saturday.
