Nothing is a given right now, and we’re all just speculating here. But I agree with much, though not all, of what you’re saying.
I would be very interested in seeing how Azzi would do as PG. Last season, after Nika came back from her injury and with Paige still out, Geno started Nika game after game as PG and not Azzi, even though Azzi is arguably one of the best players in WCBB (the best player on a team is not always the PG). To me this is the reason why I believe it’s likely Nika will be the starting PG. Whether she should be is another question. I might have a higher opinion than you of Nika’s potential for offensive improvement, but we’ll find out soon if my optimism, or more accurately my hope, is misguided.
My biggest concern is not who starts as PG. It’s the fact that five of the ten players (Nika, Dorka, Azzi, Caroline, and Aubrey) are coming off injuries. And if Nika were injured, as she was in both her first two seasons, that would complicate things a lot. Of course, IMHO.
