Who do you think were the biggest surprises? Looking at the men:
In the top 10, Pierce Murphy in 3rd was quite a run but I'm voting for Jonathan Green of Gtown in 5th. Ran 4:15, 8:08 and 14:02 last year and now he's 5th at NCAAs? Serioiusly?!
At first I did not notice "positive" so I will refrain from mentioning Texas.
