From your list, all IMHO, and with everybody healthy: (On that list, BTW, Egypt is ranked ahead of the U.S.—the same Egypt that got annihilated at the Confed. Cup—just to give a sense of the list’s value)
Definitely better than the U.S. P(U.S. Wins)<0.4
Uruguay (had us losing to them after a tie/PK win with Ghana. Then Bradley started Clark…)
Chile (beautiful attacking soccer. Pity a third of their team couldn’t play against Brazil.)
Maybe better than the U.S. P(U.S. Wins)(0.4<P<.6)
Serbia, Ivory Coast, Cameroon, Switzerland (especially with the way the U.S. fails to finish chances), Turkey, Ukraine, Romania, Denmark, Norway.
As far as Mexico goes recently, when both teams send their “A” personnel, Mexico gets beaten like a gong anywhere outside of Azteca. This year’s squad, when the coach isn’t playing Blanco, is pretty good though. (Not to say I wouldn’t love a lot of the Mexican players on the U.S. side. If they had Dos Santos, the U.S.'d probably still be alive in the tourney)
Oh, and why will the Cup come to the U.S. again in '18 or '22. Snarky Kong hit it: Cold hard cash. Same reason that Dubai or Qatar will have a shot at it. (Though in that case, when would the tourney happen and how would that fit in with everyone’s domestic league schedule? Can’t see them playing in Qatar in July…) I’m very surprised that China hasn’t put in a bid yet. Though isn’t one of the requirements that the host have (or promise to put in) a domestic soccer league? Though all of the “the U.S. just needs to siphon off 1/10 of its athletes”-type arguments work a lot better for China, with a base pop of ~4x the U.S. Look at the giant strides the Chinese track and field teams have made recently.
Finally, I could be screwing up the calcs, but the winning probability needed for the U.S. to have a 50/50 chance of winning at least one cup in 12 separate tourneys is around 0.0562, or 1/17.8 What did the U.S. go off at to win it all? 75/1 or something like that? Given those probabilities, and the fact that the Netherlands, Spain and Portugal still haven’t won it all, I voted no in the poll.
