It really depends, I think, on the player and the experience of the people around her who are helping her decide. Usually, families lack the background to make a solid decision about intercollegiate athletics, and often have distorted views of their child's abilities. And sometimes their coaches haven't been around long enough to really understand the subtleties of succeeding at the collegiate level.
Jordan came from our program at Miramonte and also Cal Stars (which I'm not involved with), so she's in a situation where she's surrounded with coaches who've dealt with the system for a long time (that doesn't guarantee no mistakes, but it lowers the odds). Her dad, Dave, was an outstanding player at Chico State and so has a feel for what goes on at the collegiate level, so my sense is that this was a decision that had a lot of thought behind it, and looks like it should work out for everyone.
But sometimes early commitment decisions are made that don't work out, so there's obviously a risk involved. The advantage, though, is that the pressure is now off, and the player can just enjoy playing and also work on improving her game, which means making more mistakes. Some players are so focused on impressing college coaches that they take few chances and only do what they're already good at, which limits their growth as a player. Once you've committed, you can focus on things you don't do as well without worrying about how it will affect your standing.
