FanGraphs Runs Allowed Projections for ROS

I know Pitcher’s Individual WAR is independent of Defense.

Question: When fangraphs lists RunsAgainst (RA) avg in Projected Standings for rest of season (for Teams), are you using projected Defensive stats (for rest of season) to come up with RoS RA?

I am assuming you have to include Def. stats to project RoS RA because by definition, pitcher WAR does not include defense.

Anyone. Please clarify. Thanks
