I think Concacaf is terrible. We topped qualifying, but watching Costa Rica, who tied the US in points during qualifying just goes to show how far behind and bad the region still is. Our team is solid, but that’s probably the best that could be said for it.
Aside from past Mexican teams, I think every side would struggle immensely and rarely get out of European qualifying groups for WC. There have been some outlier performances in WCs from CONCACAF teams (outside Mexico) but that’s much easier to do in a few matches cramped into a couple weeks than to consistently perform for a dozen matches over a couple years. None of the CONCACAF teams are good enough to do that imo. Hope Canada proves me wrong here though.
