White was my original 2010 pick with her Bizzarri-esque sprint last year. Then I heard she had to injury-redshirt track along with Schaaf and McLaughlin. They could all be way behind on training. Marino had to miss some of indoor and I don't think she quite made it to her peak in outdoors. Hasay wasn't meant to peak in XC last year, but they may train her up this time. I don't know what to make of Infeld, Kimaiyo and Lemmon. Reid is scary, had her in my top 5 last year. Babcock and Kosinski could make a big comeback. Saina may make the biggest leap if she can translate 10k success to XC.
All champs who only ran 6k for nats 1) finished in the top 10 in a collegiate nationals before they were NCAA champs and 2) never finished outside the top 30. That narrows it to Kimaiyo, McLaughlin and Schaaf. Kimaiyo is the only one of the 3 that I don't have a knock against, but I'd rate people who don't fit both prongs with better chances.
