UConn dominates in large part because it plays in a weak conference. It is far easier to keep an unblemished (or nearly unblemished) record when the majority of your schedule is comprised of mid-major teams that are pretty abysmal. If UConn had to battle game-in and game-out in the SEC, ACC, or Pac-12, I'm not sure their record would be quite what it is now.
You don't have to agree with me about the parity issue. It's really neither here nor there to me. I do know that in 2015, overall competition in the women's game is tougher and there are far more teams that consistently perform at a high level in the sport, which makes it relatively more difficult for elite teams to completely dominate the sport. (And yes, I know UConn dominates, but it dominates by playing in a mid-major conference where their next best competition probably isn't as good as he lower tier competition in the SEC.) Regardless of what you think about parity in the sport, or how you define it, the women's game has changed. There are many more teams today that can give even the best programs a run for their money on a consistent basis and that compete with the top programs for highly ranked recruits; to me, that is what parity is all about.
