The defense gave up three plays of over 25 yards throughout the course of the game, two of those were against the second- and third-string defense.
Most of the Rams offense came on short runs and check down routes to tight ends.
This is what a Bill Belichick coached defense is designed to give up. The trademark of the "bend-don't-break" defense is the soft underneath coverage.
You concede the check-down throws, but hit the receivers hard once they catch the ball, hoping to create turnovers or make the receiver think twice about coming over the middle again.
There were a few missed tackles, but for the most part, the secondary, led by Brandon Meriweather, hit the defenders quickly after they caught passes.
Some of the hits were substantial, but the Ram's receivers managed to hold on to the ball. If this hard-hitting style continues, more than a few balls will hit the turf throughout the course of the season.
The real shortcoming of the defense was in getting off the field on third down and on stopping the offense in the red zone.
The Rams were 11-of-17 on third down, and scored touchdowns in four out of six trips to the red zone.
The good news is that the game hinged on only a few plays here and there.
Getting a stop on third-and-4 on the New England 32 yard line would have resulted in a punt instead of a touchdown, keeping the game at 10-7 Rams.
Had Butler not been flagged on third-and-9 on the first drive of the third quarter, the Patriots would have gotten the ball back with around 10 minutes left in the third only down 20-14.
So while it seemed that the Patriots defense was as sorry as ever to the casual observer, it really wasn't that far away from a decent performance with a few more plays and a few less mental errors here and there.
Of course, Belichick won't paint it that way. He wants his players worried.
With the offense being so dominant, the defense will just need keep the Patriots in the games this season, not hold the opposition to under 20 points.
