MLS standings do not follow tiebreaker rules
MLS standings are not following the rules at at http://pressbox.mlssoccer.com/content/competition-rules-and-regulations. At the very least, the MLS data needs to include the Goals-For (GF) for each team, since it is the #1 tiebreaker, followed by Goal Differential.

Er, sorry for mislabeling: 1. Most Wins, 2. Goals For, 3. Goal Differential
