Yellow Cards and Red Cards can take a huge hit on your point totals. Week 11 - Check the refs. In each game preview, MLSnet shows you how many cards each game official has given over the course of the year. Watch out if a strict referee is running a match between heated rivals. Week 12 - Blocks can turn the tide.
Blocks are one of the most overlooked measures of a defender's performance.
Keep an eye on the MetroStars. The Metros' defenders have more goal-mouth blocks than any other team. Week 13 - Game previews hold a wealth of information. In addition to the referees, you can also find out some of the historical tidbits and lineup changes in the matches. Check out the previews every Tuesday evening on the Irish Spring MLS Scoreboard .
