Ravens D - worth grabbing?

They were dropped this week, i streamed the Browns already but after a trade i’ll have a free roster slot tomorrow morning - if they’re still a FA should i grab them and see if they’re actually good but had a bad week or leave them alone?

I like the Browns next week but the Ravens have some nice matchups down the road and the Browns have a tough stretch after week 4 (Ravens, Chargers, Bucs, Steelers, Falcons, Chiefs) can stream on the down weeks for the Ravens but having a potential elite D is worth the hold and look for this week right?
