Agree with your assessment of how many fantastic 4's we will have. One reason Jana is so important is along with Ice, those two might be considered 4/5's, and the most talented if inexperienced options to consume the minutes at the 5. We could always play Aaliyah some there, but I am hoping in her senior potential All American season, we can keep her at her natural and best position. I also think that Ayanna is looking more and more like the 4 is best for her as well.
With a growing consensus that Nika, Azzi, Paige and Aaliyah will start and be great, the main question mark is the 5. If one of the two additions in Ice or Jana can be ready to start, and the other provide good backup minutes we are obviously set. The talent is there, but so is the inexperience, so that development will be the main question next preseason. The backup talent at the guard positions should be terrific as well, so in some ways Ice and Jana are the final pieces of a great puzzle.
