Not sure if she can be considered "under the radar", but you and I chatted about her last night. She didn't play on the U17 team, but rather the U18 team.
On a team that featured Aja Wilson, Brianna Turner, Jessica Shephard (Nebraska), B. Mompremier (Baylor), Destinee Walker (UNC), Marina Mabrey (ND), Ariel Atkins (Texas), Recee Caldwell (UCLA) and a few others, she was the 2nd leading scorer on the team, 1st in rebounding, 1st in 3 point FG%, 4th in assists, and 3rd in steals. Much of the team is a year ahead of her, but Shephard, Mompremier, Mabrey and Walker are in her class. Still, she played better than any kid in her class and was about as good as Wilson and Turner - the top 2 kids in the class ahead of her.
That should tell you something about how special this kid is.
Oh, and Shephard and Mompremier played really well also. And Walker and Mabrey were right behind them. I think the class of 2015 is really really strong.
