Of course. I do think if you are the unicorn post that actually plays like a post in AAU, though, you are going to have an advantage. Obviously she's playing top talent, but everybody pretty much plays like a PG or wing, and the gameplanning things that can give a post headaches are pretty tough to try to implement in an AAU format. As an example, my daughter played with a girl that is now a solid DII player. Rotation player on a good D2 team as a Fr. but she would dominate a lot of future D1 players in AAU because she was one of the only traditional post players that was super physical and lived on the block.
Now, she plays on CY Select, which I remember my daughter playing against them, and they were pick you up full court, push pace all the time. I'm not sure if all their teams are like that, but she's going to run the floor better than people think.
The only time she seemed to have any problems with the pace was last year against N-F when they were playing like 14-15 girls, and subbing them in 4 and 5 at a time to press and run on EVERYTHING, while Crooks was playing pretty much every minute.
Also in regards to competition I think Garrigan played Valley either this year or last and I think it was like a 2 point loss. I might have dreamt that though.
