What are the new configurations ?
Which two players do you lose ?
Needs some meat on the bones, too much of an air question.
Why would the league want to adjudicate "new configurations" ??
Let the coaches work it out for themselves, it will lead to a variety of new tactics & strategies.
Just keep the 6-6-6 rule but on the understanding that coaches can have whatever format they want as long as it doesn't go over 6 per sector (e.g. 4-6-6, 5-5-6 etc). Once again, this leads to a variety of new tactics and game-plans which reinvigorates the old cat & mouse counter-plans as well.
