Simple and efficient doesn't equal fair or equitable. That is the problem. HSL needs to let everyone in at ALL levels, seed teams at ALL levels and then let the top 10 or so seeds get byes. Make the tournament a week longer so that the CONTACT sport of soccer only plays 2 games a week (like basketball, even though it is not a contact sport). Top team on bracket is home team regardless of seeding, like the NCAA. You beat a higher seed, you have earned the right to a home game if you are on the top line. Take bids from all 3 areas of the state (Upstate, Midlands, Coast). Winning bid hosts for 3 years. Rotate state semi-finals and final. Bid money goes to the state.
While you are at it, eliminate OT and PKs in regular season. End in a tie, it's soccer. Otherwise, during football line up the field goal units and kick best of 5 with the defense on the field from 35. Team with the best kicker wins.
