Spend about a month without thinking of Nancy scoring a basket. I don't think that is where she will impact the game. I suspect that she will score, probably easier in college than in HS. But, the effect of Nancy should be to take the lane away from the other team. When she is under the basket, people don't like to shoot over her. They throw up wild shots, hoping to draw a foul. But, she can block anything. The only thing that will keep her from being a game changer may be the officiating. She is so obvious at 6-9, and some officials, like in the state championships, call ridiculous fouls on her. But, she doesn't have to slap down at the ball. Her hands are pretty high up and difficult to shoot over. She is also mobile enough to block shots on opposite sides of the lane within a second.
Don't forget that in the midst of those who keep putting her down, there are scouts that wonder why she isn't being hailed as the next superstar. We'll see.
