The answer to your question is "periodically".
As for Aubrey's ranking, I wouldn't worry too much about it either way. The people that rank the players are human beings making subjective judgments. If it's multiple people doing the ranking, it's possible that not all of them have seen all the players, making the rankings that much more subjective. And if it's one person, they may not have seen all the players multiple times meaning that they could be making judgements on a bad game or two. I still feel it's goofy to rank a center vs a point guard because the skills required are so different that rating one of them higher than the other is kind of nonsensical. So, take ranking with a grain of salt.
Besides, it's not the rank of the player that's most important, it's what she brings to the team and how well she fits in with it. If a kid is highly ranked but is a prima donna or has a bossy, interfering parent, Geno won't go near her with a ten foot pole.
I am NOT saying any of the young women in the rankings are that way ( I don't personally know a single one of them); I'm just saying that a ranking isn't "all that" when it comes to players we want at UConn.
