The #1 yardage and scoring defense is certainly an incredible accomplishment but it doesn't happen in a vacuum. The Rams had the #14 overall offense. They produced the #11th most yards and #3 most plays. While not great, THE OFFENSE WAS A FACTOR, to the overall time of possession which helps the defense.
I realize that if you want to simply fortify your position, you can point out that they were 23rd in points so we had several losses as a result. But on the other hand, it was far better than average in keeping the ball from the opposing offense.
I don't wish to make this an argument. I just want to point out that success happens as a team and while the defense clearly outperformed the offense, they didn't accomplish it alone.
