An Argument for Parity?

Going into today's games, 10 of the 16 National League Teams are within 2 games of .500. The Exceptions are Philadelphia, San Diego and St. Louis at 10-6 on the plus side, and Houston at 6-10, Chicago and Cincinnati at 7-10 on the down side. Still everyone at +-4 after nearly 3 weeks looks pretty competitive so far.
