Unfortunately rating players doesn't provides goals. It also doesn't prevent goals. Instead, rating players might make you feel a little bit better as you channel your rage at 15 scales from 0/1 to 10. This is your chance to rate the players. Here's the scale.
0 or blank - player did not play enough to judge
1 - not a pro (USL/NASL/MLS) quality performance
4 - average USL starter
6 - average MLS starter
9 - MLS All Star
10 - MVP quality performance
You also get to reward the best non-Sounder. That could be fun?
