For a start of a competition yes but not in the middle of it, at least it should be done in the middle of it.
For example in 1998 WC in France the 2nd place playoff wasn't seeded and just a regular draw was made which was very fair imo.
The point is even if the playoffs were supposed to be seeded from the start of qualifying that was not made clear by Fifa, actually they were not supposed to be. So now that they "fiddle" with the seeding of the teams for playoffs, that just makes it pathetic. If they said from the start that they were going to be seeded I wouldn't have brought any of this up.
Well that just sucks, and it makes it less football and more political science.
Well the World Cup can be bought and that's not really kicking the ball.
Some filthy money has already gone into this seeding playoffs stuff, I just wanted to point that out.
