An impressive season-opening win over the Los Angeles Chargers showed that these Arizona Cardinals have potential to be a much-improved football team. The subsequent lopsided loss to the Seattle Seahawks on Sunday showed just how far they have to go to reach that potential and compete in the loaded NFC West.

The Seattle Seahawks were dominant in a 31-7 victory against the Arizona Cardinals to improve to 2-0.

Arizona moved the ball cleanly against the Chargers. Jacoby Brissett threw for 277 yards and a touchdown, Trey McBride caught nine passes for 95 yards and a score, and the Cardinals finished with 393 total yards and no turnovers.

The Arizona Cardinals entered Week 2 full of optimism. In a 31-7 loss to the Seattle Seahawks, they instead got a deflating return to reality.

The Seattle Seahawks could have two huge key players in defensive tackles Leonard Williams and Byron Murphy from start to finish versus the Arizona Cardinals in Week 2.

Smith-Njigba had nine receptions for 155 yards and three touchdowns, including an 82-yard score on Seattle's second play of the game when he ran by cornerback Will Johnson and safety Budda Baker couldn't catch up to him. Remarkably, the 155 yards were more than the 151 the Cardinals gained as a team.
