re: ESPN's Adrian Melville ranks top-23 US soccer players

Are there really no US soccer players of enough quality to be ranked in the top 100 in the world? Just trying to learn a little about the sport with the world cup coming up and reading lists of the top players in the world and not one list that I read lists a US player, even a list that went up to the top 100. Are we really that far behind the rest of the world? I thought we had closed the gap and were a legitimate decent quality team.
