Seahawks vs. Cardinals Prediction

Below, you’ll find my Seahawks vs. Cardinals prediction. Feel free to follow my betting pick or make your own today.

Seahawks vs. Cardinals Prediction: Seahawks -1.5 (-110). The Seahawks are starting to hit their stride after blowing a lead in the first game of the season against the 49ers. I think the Seahawks will continue to find their offensive stride to complement an exceptional defense. On the other side, the Cardinals have questions, especially with the low performances by Marvin Harrison Jr. at wide receiver.
