If the goal is parity at any "cost" (including ignoring what the student/athletes want), then it's simple. Just do away with recruiting. Go to a draft. Bottom school (based on something - maybe Sagarin or Massey rankings) chooses first. Almost impossible that a team would get two superstars. You would have several EDD and Delaware situations every year.
Of course, player development to get to the next level would be pretty problematic (Though EDD showed she was able to rise above). But for the "parity first" crowd, that is a small price to pay.
My real thought on this though is that parity STILL wouldn't exist as obviously there are some MUCH better coaching staffs than others. I'm pretty convinced that Geno, Chris, Shea, and Marissa could take an average group of kids and have them perform at an above average level.
