You used the Miss Basketball finalist at Westview as an example in your post. If you were her parents, would you have left her at South Fulton for her senior year? Assuming you had the means and a legal way to get her to Westview or any other better situation, would you not have done so? Kids and parents will always look to get to successful programs and coaches. If her family was directly contacted by a Westview coach or administrator, that's against the rules. However, it seems that most "recruiting" is done by players and/or parents. This is not illegal because there's no way to police it.
If the rumor floating around about a transfer for Westview next year is true, it will again make them significantly better. They're not the only program in West TN with transfer rumors floating around. I've heard a couple different ones for USJ and South Side. The common denominator is a history of success that people want to be a part of.
