I used to think that, but Mexico is better than any of the Asian sides for me and they struggled in qualifying. Plus North America has the US, Costa Rica and mexico in good position to get out of their group, while Asia, despite having its two best teams in weak groups, looks set to have none of their four and a half bids to the second round.
They still qualified, didn't they? The rest of CONCACAF are rubbish (on paper, anyway)
So are the Asian teams... (On paper)
