There will be pool play and championship play in the Tropical Thaw. How well a team does in pool play will determine their seeding for the championship. Seeding ties are broken in the following way: 

  1. Record in pool play                      
  2. Head-to-head*                                
  3. Goals against
  4. Goal differential
  5. Coin flip

*In the case of a two way tie head-to-head record will be used, in the case of a three way tie the seeding tie will be broken by goals against- NOT head-to-head

* In the case that a team forfeits a game, the score will be recorded as a 6-0 loss for that team.

  • Penalties will be enforced by man-up and man-down
