Continue to play poorly? Where are you getting this from? MM has praised Dowdle. He looked good playing behind a second string OL going against JAX starting defense. Davis didnt do much, but he earned the starting nod.
I dont know how the RJ situation plays out. Maybe they still consider him in the running for RB2. Or they may be considering cutting him. Based on current rotation and common sense, Dowdle and Davis are your two backups. Both are very good special team guys as well.
And if some other team cuts a guy that is an upgrade, Im sure we will be looking into that as well.
