The Rams offense was able to move the ball just enough to get into field-goal range, which it was able to do five times (one time was a fake field goal, resulting in a touchdown pass).
But even though they did just enough to stay in the game, the unit looked completely overwhelmed. As a result, they were unable to produce a single touchdown, which is ridiculous for a professional team.
The offense will need to get its act together against an even more difficult Arizona defense this Thursday.
Fourth Quarter: C-
The Rams offense was not productive in the final quarter.
In the first drive of the quarter, they sustained a long march down the field and it seemed the offense would finally end up with a touchdown, but it fell short once it neared the end zone and was once again forced to kick a field goal.
During the final drive, all the Rams had to do was move the chains with just over three minutes remaining in the game, but they failed to pick up a single first down and were forced to punt, giving Seattle another chance to win the game.
The offense was completely bailed out by the special teams and the defense.
Third Quarter: D
There's not much to say other than the offense was beyond awful in the third quarter.
Three drives in the quarter and not a single first down. They picked up a field-goal on the opening drive, but that was the result of great field position rather than solid offense.
Every score has been thanks to special teams. The offense has yet to score a touchdown, and that needs to happen in the final quarter if they want to put the game away.
Second Quarter: B
At times, the offense looked absolutely dreadful in the second quarter, but a handful of key plays kept them alive.
Brandon Gibson had a costly formation penalty, but the offense was able to overcome. Robert Turner had a bad holding call that negated a touchdown, but that turned out to be irrelevant as well.
Meanwhile, key receptions by Austin Pettis and Brian Quick kept the Rams alive during the touchdown drive.
Also, Steven Jackson and Daryl Richardson have combined for 62 yards on the ground in the first half, which has been very helpful considering most teams haven't been able to reach that rushing total in an entire game against Seattle.
But still, the offense nearly blew a great drive due to mental errors. The blocking needs to be better and they need to finish drives without special teams bailing them out.
First Quarter: B+
The offense has been moving the ball well for the most part.
Steven Jackson already has six carries for 33 yards, which is very impressive considering Seattle entered this game as the second-best run defense in the NFL.
The receivers have been running good routes and have been coming up with catches.
The offense collapsed on the first drive upon entering Seattle territory, and that's not acceptable if they want to win.
