I could go with that in high school (only in the championship game because of time)... First, increase the game time to 90 minutes (should be done for all games). Next, increase your overtime to 30 minutes (2x15), then add another 30 minutes of golden goal (2x15). After 2 and a half hours you're bound to get a winner. Then, if it's still tied and they can still walk... they shoot PK's. Survival of the fittest!
