The nRd spring is w=easy enough to check. You'd know at a glance of the sagging lower loop if it were bad. Or you can shift to any mid or high range combination. Pull the lower loop down at the center, and the RD should rebound and pull it back up when you let go. That's all the RD spring does, so it's yes it takes up slack, or no the chain sags.
