Run Defense concerns

I honestly was not as scared of the Steelers as I am worried about the Falcons since I knew CJ Stroud could pick apart their defense and how good or Oline has been. HOWEVER, i am still not convinced about our run defense after how awful it looked vs the Colts in week 2 and vs the Ravens. It goes without saying, but Atlanta is going to be the best rushing team we've faced so far. Thoughts?
