Wade Phillips is one of the finest defensive minds in the game today, so he's aware of what happened to the Rams on Sunday.
Phillips believes it boils down to chemistry for a collection of Rams still adjusting to his 3-4 scheme.
While Aaron Donald remains a beast up front, former end Robert Quinn is playing his first-ever snaps at outside linebacker. Meanwhile, the team's two inside linebacker spots -- the heart of a good run defense in a three-man front -- are occupied by Alec Ogletree and Mark Barron. Ogletree played on the outside in years past while Barron was initially drafted as a safety.
"The two inside guys have played linebacker, but they haven't played a 3-4," Phillips said, per The Orange County Register. "And even the safeties knowing where to fill [in run defense], those kind of things. It just took some live-action time. Unfortunately, we didn't do as well as we wanted to, but I think we'll do better."
"We're upset about that, but we're going to do something about it," Phillips said, while saying of the Niners: "They've got to be licking their chops."
