I believe some SC teams made it to quarters, but no further. If you have never been to regionals or seen this level of soccer it may be easy to say that no SC team "won anything," but look at the scoreboard for regionals and nationals. MANY 1-0 matches, many teams virtually identical.
Teams had to play Sat and Sun for 25-min halves—no full matches. Often on soaked, flooded fields with high sod. A few were moved to some nice turf fields. But regionals were survival events this year. SC teams who were there were already winners, right?
For example, in U18G, the past two regional champs were Greensboro and Dallas. Greensboro finished last in pool play and did not advance, and Dallas (most recent champ) fell in quarters (advancing to quarters by 1-0, 1-0, 0-0). "Winning" at regionals is a razor thin event.
