Your other point about guys makes no sense whatsoever. Oregon spends their money on the guys side on distance runners and field athletes. The few athletes that they do recruit and give money to as sprinters have improved drastically and been pretty incredible. Just to name a few...
1) Devon Allen.... I don't even need to say anything about him. .
2) Marcus Chambers got 2nd in the NCAA's last year as a SOPH and ran 45.21
3) Arthur Delaney ran 20.52 and placed 7th in the NCAA in 2014
4) Jonathan Cabral got SECOND in NCAA in the 110h in the absence of Devon Allen last year.
The only thing that I 'm seeing is that Oregon male sprinters are nowhere near the females, there is not even one guy capable of going sub 10"20 over 100m flat in your list. So yes it makes sense...
