Nice speech from Renji (that remembered me a short segment that I liked, when it was becoming a neverending fights succession).
Of course, the fathers only came for a delivery, the heroes side would be too powerful if they actively participated. Having them suddenly appear a few chapters ago was only a way to show them before the finale and "keep" the readers excited, I suppose...
... Just like Aizen's reappearance in this chapter.
