Short answer: not a sustainable prospect. Unless you have the world's most understanding coaches. DD did TB and AAU for two years (6th and 7th grade). She was still on a B-level TB team at that time so the travel demands weren't huge, but there were a lot of overlapping tournaments and practices. DD then took stock; given that she is 5'4" and had already stopped growing at that point, she stopped playing basketball. She considered trying school basketball, but there are an unusual number of very tall basketball girls in her grade, so she finally said nah. I liked watching her play basketball, but wasn't devastated to have one thing off her plate. I do believe that travel softball and HS basketball are compatible; in GA, we play school softball in the fall, which sometimes bleeds over into basketball season if you make the playoffs, but not by much.
