I am not from America either, but if I was going to include players based upon their contribution to american soccer, then Paul Caliguiri should have topped the list, with Tony Meola second.
Here's a list:
1. Landon Donovan
2. Damarcus Beasley
3. Brad Friedel
4. John O'brien
5. Claudio Reyna
5. Tony Sanneh
6. Earney Stewart
7. Joe Max Moore
Right well, a lot of people, and not just americans would disagree with you. I am one of them. So I am enjoying all kinds of great players from America and you aren't. That seems like I am getting the better deal.
