Kyler Murray Sleeper Free Pick
Kyler Murray enters Thursday’s matchup looking to keep Arizona’s offense competitive against a Seahawks defense that has shown both flashes of strength and vulnerability through the air. With his line set at just 0.5 passing yards, it’s essentially a free square to help anchor your Sleeper entry.
Pair this promo pick with another star from the Cardinals-Seahawks game or another NFL Week 4 matchup to maximize value.

Cardinals vs. Seahawks Game Preview
This NFC West rivalry has delivered plenty of fireworks in recent years. Here’s what to know heading into Thursday night:
- Cardinals Outlook: Murray’s mobility and big-play ability make Arizona dangerous, especially with weapons like Marvin Harrison Jr and Trey Benson. The question will be whether their offensive line can keep Seattle’s pass rush at bay.
- Seahawks Outlook: Kenneth Walker III runs the show literally and figuratively for Seattle.
- Key Storyline: Can Arizona’s defense slow down Seattle at home, or will Murray have to put the team on his back in a high-scoring shootout?
