The first sentence of my previous post brought to your attention that since international rules would prevent Lagat from running for the US in Athens, there was absolutely no reason to use the line "a guy who changed citizenship before last year's olympics but for some reason didn't feel the need to be a real american and run for his new country".
You admit yourself it is completely irrelevant and it only diminishes your (virtually non-existant) case to bring it up.
You also seem to be in a downward spiral as to your definition of what it means to be a true USAnian. I can't see any logic to your concept that one year of a US high school means more to an athlete's development than 4 - 5 years of the NCAA system. Just because you arbitrarily define it, does not make it so without justification. That is why it is of relevance how many 'home-grown' stars were developed by the high school versus the university system.
For a country that bills itself as a great global melting pot and second to none in most fields of endeavour, to say that the fact there are many foreigners in the NCAA means that USAnian runners training and competing against them are not real USAnians seems a bit contradictory to this Canuck. Maybe that's just your own domestic psychosis at work.
David Morris was essentially a non-entity on the US national scene before he headed off the Japan. A few years there and he sets a national record. You still have not explained logically why that is ok, but someone who was a solid university runner and developed into an Olympic silver medalist in the US is not.
On a bit of a tangent, should all those Kenyans who went through St Patrick's not be eligible for Kenyan records since Coach Brother Colm is Irish?
