The Los Angeles Rams may be sitting at a perfect 5-0, but that's not enough to keep Pro Bowl nose tackle Ndamukong Suh satisfied.

One of only two undefeated teams left in the NFL (the Kansas City Chiefs being the other), the Rams barely escaped with a 33-31 road win over the Seattle Seahawks in Week 5. Before that, the Rams just got by the Minnesota Vikings in Week 4 with a 38-31 victory in an offensive slugfest.

The Rams defense hasn't played up to its usual level of dominance recently, however, and Suh expressed his frustration about it.

"Terrible, without question," Suh said, via Lindsey Thiry of ESPN.com. "That's my personal opinion... It's terrible just from a standpoint of how much run yardage we gave up."

Los Angeles held the Minnesota ground game to just 54 yards, holding Dalvin Cook to 20 yards on 10 carries. It was quarterback Kirk Cousins who led Minny's ground game with a mere 28 rushing yards on four carries.

But when the Rams visited the Seahawks in Week 5, it was a completely different story. Chris Carson rushed for 116 yards against LA, and the Seahawks totaled 190 yards on the ground. Seattle averaged 5.9 yards per carry against the Rams, who had no answer for a ground game that had been struggling for several weeks.

The Rams defense ranks 18th against the rushing game, allowing 106.8 yards per game. A defense that consists of Aaron Donald and Suh obviously expects to be better than that, but it's not as though this is a wretched unit in general.

LA ranks 10th in yardage defense and seventh in scoring defense. They may have had a rough outing against the Seahawks, but this is still a top-tier unit that has propelled Los Angeles to an impressive 5-0 start.

Los Angeles visits the struggling 2-3 Denver Broncos this Sunday, looking to move to 6-0 on the season. Denver's offense has been abysmal since a 2-0 start, so Suh and co. have an ideal chance to turn the "terrible" rushing defense around.
