So here's my take. Mikayla hadn't played much in 2 years and was unlikely to play much in the next two years. However, there is a window for at least 1 starter on next year's team, as well as a 6th man. If the Huskies go any deeper than 6 players it'll be a miracle, but as I've said many times before, nobody goes much deeper than 6 players in big games.
Mikayla will have had her post-season review with Geno and there would certainly have been a discussion of how much PT she could expect next year, and what she had to do to earn it. Others may disagree, but if UConn does not bring in another player, based on who's returning along with one talented, but undeveloped freshman, Mikayla would very likely be UConn's 5th starter next year. She was the 2nd player off the bench down the stretch. A healthy Batouly might be a better option as the 5th starter, but sadly I don't think that is in the cards. Had Geno communicated to Mikayla that he was counting on her next season, I think there is a very good chance that she would have stayed. The one thing I would absolutely expect is that Geno would be completely honest with Mikayla.
So the logical conclusion is that Geno has someone else in mind as the 5th starter and perhaps the 6th man as well. We can certainly speculate: Makurat, Westbrook, Laksa, TBD? I believe that all of our questions will be answered in the next few weeks. Until then, try to stay calm and enjoy the warm weather.
