I don't think there is enough there, but I cannot be sure without knowing how much you started with. The top of the plant looks great. I don't think I would have done much to it until I started seeing something in the plant, or let it sit out overnight to really get a picture of what the roots looked like when starting to dry. I don't think you could have had that much root rot with such a healthy plant at that size. Dreamer maybe able to give you more info.
