Sean Carlson was only hired two years ago. Dylan Jacobs and Yared Nuguse are two of his former athletes. You'd have to go far and wide to find coaches at sea level in the United States who have produced two better quality, top tier middle distance runners than them. Nuguse is the fastest American miler ever by three seconds, and before you say it was Ritz that made him that, recall that he had already broken the NCAA 1500m record in a conference heat at Notre Dame. So, give him some time to produce a powerhouse Tennessee program, just as it took Vin time to produce top tier results at UVA.
