You are all assuming that Nika won't make a sophomore jump? Admittedly not all players do, but with her apparent drive and what we hear of her work ethic, I think it's reasonable to assume that she will improve going into next season. Azzi has a reputation of being a can't miss player and she very likely is, but she hasn't even had a college level practice yet. It might be a little early to anoint her, although Milford may think otherwise.
In any case, there will be a lively debate about the starting five during the offseason, as there always is.
As for Saylor, she arrived on campus in the middle of the season. I imagine there was very little "teaching of he system" at that point. What she is learning she is absorbing herself. I doubt the coaching staff has much time for her at this point as they are focusing on preparing for the tournaments. As an analogy, Saylor is taking introductory courses via distance learning. The core seven (or eight) for the tournament are getting graduate level one on one in person instruction. That is as it should be at this point.
Miles and the young lady at Oregon State are playing because those teams had holes in their rosters that they had no one else to fill and, to their credit, they are making a positive impact for their teams.
