CONCACAF

Here is an excellent post about CONCACAF's historically strongest teams in the 146 editions of the FIFA rankings since 1993. It's a bit sad to see how poorly Canada has compared to much poorer and smaller countries, but hopefully that will turn around in the next few years. In a subsequent post, he ranks the CONCACAF teams historically with the following list:
