Well, we all agree on 4 slots with PG being the only question.
IMHO, Fletcher will start in the early season. Her experience (though in a different system) will provide a more calming influence. Plus, Raven may not be in great playing shape early in the season after her knee surgery. Raven may take over the starting role later in the season.
Also, we heard a lot last year about the excellent chemistry between Raven and Kamilla. I could see them being paired on the court together a lot (early) as the first players off the bench to rest Boston and Fletcher for significant minutes.
I agree with this - Raven really didn't get much playing experience last season due to her injury, and I expect the early-season non-conference schedule to be just as tough as last season's was. Plus Raven is still finding her way back athletically from the injury - I am thinking of a scenario similar to Coates' freshman and sophomore seasons, and Wilson's freshman season, where both came off the bench after the 1st and 3rd Periods, played half the game (20.0 mpg ~), and ended up being two of the better players for the team.
I see Fletcher starting early in the season with her substantial experience, and Raven coming in and playing around 20 mpg depending on well her game catches up. Raven is still the heir apparent - she's a red-shirt freshman, so it's not any different than she was expected to contribute last season behind Henderson before her injury - and this will be Fletcher's 5th and final season of playing eligibility, I believe. So it's sort of a reboot of what last season was supposed to be for Raven, only then with Henderson mentoring her......
