Yes I am, I will admit I am naïve in this whole area, but it just doesn't make sense to me! Ha!
.................There shouldn't be dozens of teams unless they can all compete at the top top level, which people on this forum are disputing.
If your kid stays with soccer into olders, perhaps you'll change your mind. If this is your first time through the ages, its natural that your perspective is heavily shaped by what you know, and not know what you don't know.
As for number of teams, there are exactly 12 teams (a dozen, not dozens) from U15 and above in boys SW conference. And if you up to U17/16, that number drops to 11 teams and by the time you get to U19/18, there are 10 teams in SW, or Total of 19 teams in the entire western region (SW+NW) - from Vancouver Canada to San Diego, as far east as Salt Lake City and Casa Grande in AZ.
Just keep an open mind and you'll discover that there's a whole different complexity to youth soccer through the ages.
