If they did, it would be one of the shortest lawsuits in history. First, the fact that HS girls have opportunities to attend college ID camps both during and outside HS season, when that is apparently not an option for male football players, is actually a benefit to girls because they have more options. So, unless you're trying to suggest that the boys have a Title IX claim because they are getting screwed because the University of Alabama only has camps in the spring, it makes no sense that girls are being deprived anything because they have more options.
Second, because HS boys and girls both have the opportunity to attend HS soccer ID camps during the season, there is no disparate treatment because boys and girls have the same opportunities.
Third, a HS and CIF have no control over when colleges ID camps. They are therefore not discriminating against anyone or depriving anyone of an opportunity because it is not taking any adverse action against a kid.
Fourth, the last time I checked, the weather cannot be a Title IX defendant although it is the reason soccer is played in winter in CA but, drumroll please, at the same time as football in Michigan and New York. Honestly, it's pretty myopic and self-absorbed to assume that everything is exactly the same as where you happen to be.
