We've written an article about the new standards which you can find here:
We have a lot of unanswered questions.
We really believe any country with 3 people ranked high enough to go should be allowed to send any three that they want. That will protect the integrity of the US Olympic Trials - the greatest meet in North America - and also up and comers or those coming back from injury.
I also did some quick research to see how it would play out in the marathon.
American Chris Derrick is ranked 319 in the marathon right now. BUt if you take out all of the people from Kenya/Ethiopia after 3, he moves all the way up to the top 60 and they take 80 for the marathon.
