I'm sure she is not rated #1 without a lot of talent, but the videos I have scene don't have her getting up in the air.
She's not going thru a college practice or training yet and rebounding isn't all abt vertical leaping it's position and desire too. Nice form on her shot, ran the floor well, uses the backboard on her layup shots with both hands, pursues and grabs rebounds like she gets a gold coin for each one. I remember a young Aliyah Boston and she had weight and she turned out ok.
