With such a young group of skill position players it was expected that the Rams would have some ups and downs on offense this season. No one however expected the kind of “down” that took place in Week 4 against San Francisco. Anytime you’re below 200 yards in total offense and don’t reach the teens in points scored it’s a bad day at the office. And the Rams were at 188 yards and 11 points in their 35-11 drubbing against San Francisco. In completing only 46.3 percent of his passes (19 of 41) throwing an interception and losing a fumble it was one of quarterback Sam Bradford’s worst days as a pro. The fact that it all took place on national television in prime time made matters that much worse. Bradford sat staring into his locker stall for what seemed like an eternity after the game his frustration obvious. “I was very frustrated” Bradford said Wednesday nearly a week later. “Last week was definitely one of the tougher games that I’ve had just knowing how good this offense can be and the way that we can play. To perform the way that we did it was very frustrating.” Over the past two games 24-point losses to Dallas and San Francisco in which the Rams were outscored 66-18 Bradford was sacked 11 times hit 15 additional times and pressured (where he wasn’t hit but had to hurry his throw) on 15 more occasions. Put it all together and Bradford was sacked hit or pressured 41 times according to Post-Dispatch film study of those two games. He looked a little gun-shy in the second half of the San Francisco game and by the end of the game 49ers defensive backs were aggressively jumping the underneath routes making it all but impossible to get any rhythm in the passing game. Was that a case of the Rams simply getting too predictable on offense? “I don’t think so” offensive coordinator Brian Schottenheimer said. “I think (the 49ers) felt like they were getting pretty good pressure on Sam. So I think they felt the ball was going to come out pretty quick. “They were matching all the stuff underneath which means there were guys playing zone behind it and they’re ‘manning’ everything up underneath. That kind of makes it hard. ... There’s certain plays I’d like to have back that I called. But I don’t think it was anything other than the fact that we just didn’t execute very well.” Making matters worse in the Thursday night game was the fact that Bradford was as inaccurate as he has been in a while. He missed what would’ve been a sure touchdown pass to Austin Pettis on a busted coverage by the 49ers. He had a defender in his face and was hit on the play by Ray McDonald who got around right guard Harvey Dahl. Even so just a little air under the throw and it’s seven points. Later in the game Bradford slightly underthrew a deep ball to Brian Quick. Quick could have done a better job fighting for the ball. But the ball was tipped and intercepted in the end zone — another potential seven points gone awry.
