I know people don't like this approach, but give him some time. Any runner interviewed while down and out is going to present himself as most likely being washed up, or at least as incapable of ever running as fast as he once did. Josh struggled mightily for a couple years, and is now coming off a teaser of a stretch in which he got just healthy enough to train hard enough to *not* come back and race. He's only 24, but of course he's going to sound like he's 34 and cooked because all he has is his own perspective. And when questioned by a journalist about the whys of his injuries, he or anyone will naturally look for a culprit by way of just trying to answer an often answerless question. Maybe it was his strength regimen, maybe not. But Josh is a smart, thoughtful guy who seems to know himself pretty well.
People here wrote off Goucher, including (by the sound of it if not in reality) Adam Goucher, and then he was back. Paul McMullen was back up to 200 pounds and missing some toes, and *he* came back to run as well as before. Stories like this are never guaranteed, but they are not rare. Peter Maher, Judi St. Hiliare, Stephanie Herbst, Webb if you care to count him, Gabe Je...well, not so much, but anyway. I wouldn't write of Josh McDougal quite yet.
