Did some more research. Sang makes the most sense among the top 10, as I don't see anyone else going anywhere (The only person that looks like they might have eligibility left is Amy-Eloise Neal, who would be in her sixth year, but would have had two seasons of medical redshirts and could theoretically apply for another year of running eligibility). Sang would not need a release from UNC-Charlotte if she completes her finance degree this year. I dug a little deeper into Kurgat's claim that she is 22 and not 26 as the IAAF site states. If Sang is indeed her sister (both's father is named Kipsang, but one lists the last name as Rutto, where as the other lists the last name as Kurgat), and she claims to be 22, then she would be one month and one week younger than her sister. So either Kipsang was maintaining a polyamorous relationship (not uncommon in Africa) or someone is not being entirely truthful. One other thing I found interesting was Charlotte Taylor already had a college degree in England before going to USF for three years of running in graduate school at USF (she will be 24 years old in January). Can someone explain why a US collegian's 5 year eligibility clock starts the moment they enroll in college, but a foreign athlete's clock starts later? Seems like that just encourages coaches to pull more older foreign athletes.
