These guys aren't scrubs. Both are products of the NCAA.
Lenny Korir won two NCAA titles, beating Chelanga and Sambu, no Americans in sight (I think this was the year Chris Derrick was banged up.) I think both titles were NCAA meet records at the time. He ran 13:19/27:29 in college. He won the NYC Half last year outkicking 26:54 man Stephen Sambu.
Shadrack Kipchirchir ran 27:36 in college and finished a close 2nd to Cheserek that year, and showing a kick that nearly responded to Cheserek's.
They are good. They both have college degrees already. The WCAP program is also giving these guys better life and career skills.
Also, no shit they are looking out for their best interests and taking advantage of their opportunities. I am. You are. That's the epitome of the American Dream. You don't need to grandstand about the American Dream if you're just trying to eke out a living. Work your ass off, make a living off your talents...Self interest is a powerful motivator. What's wrong with looking out for #1? That's capitalism. Doesn't matter their intentions, though I doubt you've spoken a word to either of them to determine how well-intentioned they are.
