Despite being 26 Sammy has only been running 5 years, whereas someone like Derrick has been running since middle school. I find that the group of people who complain about Africans winning titles are not concerned with the state of distance running in America, older competition, or foreigners in the NCAA. This group is simply suffering from prejudiced beliefs. For instance, whenever an African wins an NCAA title this group goes off with jeremiads. Yet where were they when these foreigners won NCAA titles:
Not to mention the Aussie in the steeple, and of course the kiwi Lucy Van Dalen
You can't tell these people aren't Americans because they are white. Whereas it is obvious who is African. Laslty, in proportion to Americans Africans have not won very many titles. If you do research you will see that there have been turns in domination of distance running--remember Japan?
