On the boys' and girls' sides, not a lot of stalwart professional runners from the ranks of the Footlocker xc winners.
For the boys, Drew Hunter (2015/Tinman) just qualified for World's, though not close to the top three overall.
Cheserek (2011-12/college-Oregon, Andy Powell and Vin?) is not eligible for the USA but would likely have qualified for World's for the USA or Kenya. Then there is Solinsky (2002/college-Wisconsin, Jerry Schumacher), who ran 12:55 twice and 12:56, as well as 26:59 before suffering a bad non-running injury, Dathan Ritzenhein (1999-2000/Colorado, Wetmore), who qualified for numerous teams and ran 8:11/12:56 AR/27:22/60:00/2:07:47, and Jorge Torres (1998/Colorado, Wetmore), who had a short professional career but a fine college career and qualified for an Olympics or World championship in the 10000m. Matt Downin, Adam Goucher, Reuben Reina (1985), Marc Davis (1986), and Bob Kennedy (1987, Indiana) were all good in college and Kennedy obviously had multiple American records at the 5000m (12:58) and World and Olympic teams. The chances of boys' winners becoming really good later are much higher than the girls winners. (Grant Fisher is another multi-time winner who has a shot at future U.S. teams).
On the girls' side, Jordan Hasay (2005, 2008/college-Oregon, Powells and Vin) has run 2:20, Sara Bei (2000/Hall-Stanford, Vin) has had a good career, and then you go all the way back to 1984 with Cathy Schiro (O'Brien, qualified in high school for the Olympic marathon, I think). That really says that there's not a lot to say for being great at the distances as a teenage girl.
