An organization may have 1 go for black. If they don't qualify then 2 teams can go for white. They may also have a silver. If both teams make white then it is 2 white and 1 in silver. If only one makes white then it is 1 in white and 2 in silver. If they can't even qualify 1 team for white then they are playing in the wrong league and all of the coaches and directors should be fired.
All of these quotas just serve to make the parity process less efficient. Who cares if there are two Islander teams in black if they are both good enough? Enough with the regulations, just let the "market" take care of things with wins and losses as the sole criteria.
