I was directed to another MLS Fantasy Guide earlier today and it has some pretty cool elements that I don't really plan on including in mine. Two of the most useful parts of this site is the "set pieces" page and the "players out page". I really hope the author of this site maintains it as it will prove to be a useful resource.
I didn't see which game this site was specific to, which makes a huge difference for player evaluation. There are some things I think this guy gets wrong (like listing several defensive midfielders in the top 3 options for their team), but I'll surely be checking in on it periodically.
