Personally, looking at Tegenkamps most recent and past performances, he is the best American athlete in both the 5k or 10k distance. He could win either at the USATF championships and for some reason everyone is so hyped about Ritz having run 8:11 that it seems to overshadow Tegenkamps 8:07 in the same race. He is at a far more superior level than any other American right now.
