"Race" and nationality as I see it are different. Alabama is a bullshit xc program because it just imports Kenyans.
An American kid with black blood is an American recruit with American upbringing. I see it in ncaa swimming. NC State has become a national power but most of their team is European.
I don't get why when an American born runner does well the coach is credited with developing them.
When a non-American born runner does well, the coach is viewed as having nothing to do with it - they just imported the talent.
If it was simply about developing talent, Oregon wouldn't be allowed to take transfers and wouldn't recruit so many FL finallists every year.
