And the lowered field results in just 32 teams contending at the core site. All individuals have to publish a minimal.500 conference report - the "Lunardi Rule" - for at-large consideration.16-Team BracketIn this projection, the board decides on and seeds the 16 ideal accessible teams. There are actually no automated qualifiers, although all non-competing event champs get the designated profits unit.To sustain some feeling of national balance, event participation is topped at four staffs. As well as no location shall have more than one group from the same event.
