Personally I find the whole ranking and pot system for the World Cup to be broken. First the rankings. How in the world is Switzerland ranked high enough to be a seeded team? I've seen them play and they aren't that great. They got extremely lucky in the draw for UEFA qualifying, being put in a group with Norway, Slovenia, Iceland, Albania, and Cyprus. They got to the World Cup without playing anyone of consequence and got rewarded with an absurdly high FIFA ranking and a seed in the World Cup. They aren't even the 8th best team in Europe let alone the World.
Next the pots. Doing the pots by rankings for one pot and Confederations for the others is ridiculous. The rankings may be have some silliness like Switzerland being 8th, but putting teams together in the same pot based on Confederation means you're treating all teams in the same Confederation as equal regardless of their performance in qualifying. So the US gets no credit for their dominant qualifying campaign and Mexico gets no penalty even though they almost failed to qualify.
I think they need to fix the ranking system first and then do pots based on rankings rather than Confederation.
I think Blatter's talk of adding African and Asian teams at the expense of European and South American teams is really aimed at throwing bones to the third world countries that are his power base and sticking it to Europe and South America, from which he will most likely get his most serious challenge in the next FIFA election. UEFA may have a lot of weaker sisters in their Confederation, but they also have a lot of strong teams. What they need to do is revamp their qualifying process to weed out the weaker teams early in qualifying, as CONCACAF does with the Caribbean nations.
The next three World Cups should be interesting in that each one has the potential of being a disaster of epic proportions. Brazil may not have been a bad idea when they chose it, but changes in the economy have caused a lot of problems and there are already massive protests about the World Cup. If the Brazilians don't do well on home soil, it could become a powder keg of unrest. I wonder if the government is reconsidering whether it was a good idea to host both the World Cup and the Olympics in the same cycle. Each is in and of itself an expensive undertaking even in the best of economies. I can't imagine how much hosting both is putting a stain on the finances of Brazil and Rio de Janeiro. The next up is Russia, which seems to have returned to the days of repressing it's people and bullying it's neighbors. Then you have Qatar, with it's ridiculous heat and allegations of using what amounts to slave labor to build its World Cup facilities. Somehow I think when they pick the host of 2026, we'll see a very safe choice just because Blatter may well be gone and the FIFA powers might be looking for a host with as few headaches as possible.
