The Ravens D doesn't have the same talent the Rams have. That D secondary and team, in general, has been ravaged by injuries.

They don't have a pass rusher like Donald and the Dline, in general, are fairly close in talent to what the Rams have, They don't have anyone close To Fuller, Ramsey or Williams left in the secondary, the Rams secondary has severely disappointed this season at least so far, I am not sure if it's just them, coaching, or what or how they are being used or what they are being asked to do. It shouldn't have changed much from last season outside of JJ3 being gone, his value as a leader and stabilizing force back there was undervalued at least to me.

The Ravens D is just called and run differently than the Rams, they are much more into presnap aggressiveness than the Rams are.
