GLENDALE, Ariz. — On a play that didn't particularly matter in the final seconds of the fourth quarter, Seattle's defense was swarming anyway, chasing Arizona's Kyler Murray across the field before the quarterback dejectedly slid to the ground for a sack as the clock hit zero.
The Seahawks have proved they have a good team. Now they want to be great.
Their 30-18 victory over the Cardinals on Sunday suggests they're at least trending toward that goal. Seattle (8-5) has won four straight games and maintained its one-game lead in the NFC West.
''We didn't want them to score,'' linebacker Ernest Jones IV said of the final play. ''We want to be dominant. And you can't just be dominant at certain times, you have to be dominant throughout the game.''
After a slow start, the Seahawks controlled the final 3 1/2 quarters. Zach Charbonnet ran for a career-high 134 yards and two touchdowns, Geno Smith threw for 233 yards and a score, and the defense had two crucial interceptions in the first quarter.
The Seahawks swept the season series from the Cardinals. They have won seven in a row against their division rival.
Seattle shook off an early deficit to take a 24-10 lead by halftime. Charbonnet broke a tackle at midfield and sprinted 51 yards for a touchdown with 2:36 left in the second quarter.
The 23-year-old Charbonnet thrived in an increased role, taking over for injured starter Kenneth Walker III. The second-year player also caught seven passes for 59 yards.
