I am not sure how much it hurts Gilman's seeding. Where did you expect him to be seeded and where will he be seeded now?He is a top 5 guy no matter where he is. How he wrestles in St. Louis will be far more important than his seed. He can beat any of the other top 4-5 guys and he can lose to them.
The other factor is who will get Delgado in the quarters. You have to figure Delgado is going to be around a 6 or 7 seed at best and a 11-12 seed at worst. I can't imaging that they will just throw him into the draw.
