If they weren't worried then, the Arizona Cardinals are concerned now.
After struggling through the preseason offensively, the Cardinals' attack sputtered again in a 20-16 loss to the San Francisco 49ers Sept. 13 at University of Arizona Stadium. The Cardinals are taking this week to improve and make sure this week's game against the Jacksonville Jaguars Sept. 20 on the road is different.
"You're dang right we're upset," safety Adrian Wilson told The Arizona Republic. "and that's why there's going to be a lot of yelling around here in the next 48 hours."
The Cardinals are looking for more production after a disappointing performance. Arizona gained just 299 yards of total offense. Quarterback Kurt Warner threw two interceptions and the Cardinals gained just 40 yards on the ground.
When the Cardinals begin preparation for the Jaguars Wednesday, the focus will be on making sure there is not a repeat of Week One.
The Cardinals would like to make sure they create plays and not take them away. Arizona, on top of its two turnovers, committed 12 penalties.
Despite the offensive problems, the Arizona defense played well holding San Francisco to 203 total yards and 19 yards rushing.
"They kept us in the game in the first half and played very well," Whisenhunt said. "If we can hold teams to 203 yards of total offense and we get our offense going, which I expect us to do, we are going to win some games."
A subpar performance has captured the Cardinals' attention. They're worried. Another performance such as that could have them scared.
