If you took the indoor season best of the top 4 college American's this year it adds up to 3:02.13
Arman Hall 45.28
Vernon Norwood 45.39
Brycen Spratling 45.57
Christopher Giesting 45.89
USATF and the NCAA really need to work together to start scheduling so that the top American's actually represent United States in international competition.
There are several events that it was harder to qualify for the NCAA's than the USA indoor championships. I understand there are some international students in NCAA, but some events even if you take them out they are still more competitive than the USATF indoors.
