A short week and having to travel aided the demise of a 4-0 Cardinals start to the season. An offense that couldn't produce any points allowed its quarterback Kevin Kolb to spend the majority of the evening getting up off the ground. The Rams' defense recorded a team-record nine sacks - three from Robert Quinn - against a Cardinals team that gave up eight sacks last week.
Kolb finished with 289 yards passing but could not produce in the red zone as the Cardinals were held scoreless for the final three periods.
Rams quarterback Sam Bradford struggled all evening but was able to produce two touchdowns, including a 51-yard bomb to wide receiver Chris Givens, despite going 7 for 21 passing.
The Rams improved to 3-2 on the season while the Cardinals fell to 4-1. They will still hold at least a share of the NFC West lead no matter the outcome of the second-place San Francisco 49ers contest against the Buffalo Bills on Sunday.
