Interesting. I haven't perceived her problem as a lack of confidence but rather one of judgement. What she can and can't do. She is extremely talented but can't run over the opposition on the college level like she did in high school. Not yet anyway. Everyone has an adjustment period coming into wcb. It's a learning experience and with her talent I have no doubt that she will excel given time to adjust.
No other than her can be in her head and no what's truly going on, so this is obviously a guess.
But when I see her play, I see someone who's let the hype get to her head, who feels a responsibility for making absolutely everything happen on the offensive end. She can be a dominant player, but she needs to go to her strengths a little more, she needs to start hitting her shots and, most importantly she needs to let the offense come to her a little. Good games, against anyone, will increase her confidence. That confidence will allow her to realize that, as a freshman, she doesn't need to be the be all end all for her team to win.
