FIFA ranking system is still so whacked. They'll never come up with a proper system.
Costa Rica, on the basis of mean nothing wins in the last week of qualifying jump several spots to 31, vaulting Canada, who finish first in Concacaf while dropping several spots to 38. The ranking movements due to the Costa Rica wins and Canada losses but with no consideration that the W against Canada was while Canada played more than an hour red carded, down a man, and the US layed down in their last match. One thinks if this is the first round of qualifying the results don't go this way. Something for Costa Rica to feel good about I guess.
Hopefully for Canada the latest loss doesn't screw up their placing in the draw in anyway. From what others have stated it changes the pot they will be in. tbh I don't understand the pot system any more than I comprehend voodoo.
