Ratcliffe is clearly a talent of unusual magnitude. He's barely been healthy enough to race for most of his college career, yet he's able to mix it up the foreigners and others.
If he is able to stay healthy, he can probably break Rupp's AR if he makes the same basic choices: Hard training, a monastic life, and always, always using the most cutting-edge legal supplements and aids to approach -- but never cross -- that dreaded line into corruption. If Radcliffe can associate himself with a driven coach like Alberto Salazar while remaining just outside whatever unfortunate sleaze is likely to eventually erupt from that situation, and embellish his body with only the grayest of gray-area boosts (and being careful to study over a period of at least 10 years how people might try to paint you as a cheater using Testoboost cream).
If he's lucky enough to run at the level of any number of dopers without doing it, as Rupp has, we can all root for him to be the next great American, as we've done for Galen Rupp.
