Here is one reason why. We don't participate in international scouting networks and ID services like over 200 clubs do from around the world, including MLS Clubs like FC Dallas, DC, LA, Chicago, Chivas, Columbus, Montreal, New England, NYRB, Portland, RSL, San Jose and Vancouver.
This resource is good enough for those clubs, and FC Barcelona, Liverpool, Arsenal, AC Milan, Inter, Galatasaray, Boca Juniors and more. Not to worry though, we don't need to be in this, we have Paul Mariner and Earl Cochrane looking for about 8 or 9 good players.
This is the resource I am referring to
