With the discussion of tutoring seeming to focus on Amari, I'm noy sure if the person who could benefit the most wouldn't be Ayanna. Amari has tools, but is neither quick nor physical. Whatever tutoring that takes place is dependent on what that player has to work with.
Looking at our other young bigs, Ice was coming to us as a fairly developed big as far as her offensive game was concerned. She has a number of go to low post moves, plays under control and adds a mid-range jumper to the mix. Ayanna is the better pure athlete by far, but has relied on her athletic ability alone to score inside. She didn't need to worry about creating space, having go to and counter moves, using hesitation etc., she just gets the ball goes up and frequently at this level gets blocked.
What worked in HS doesn't here, she needs to expand her game and play more under control. Everything seems rushed and sometimes she is out of control. Having said those things, I think she more than anyone would benefit from a good post tutor. Amari could too, but her tools and abilities are different, and Ayanna is so raw and yet with so much potential, that I think working with a talented big would help her even more than Amari.
