Doug, I think you are a great poster here, and I understand exactly what you are trying to say, but your definition of "athlete" does not match what the general populous would call an athlete. The very BA article you linked/quoted mentions Hamilton's "off-the-charts athleticism".
That said, the folks in this thread projecting anything more than 12 HR for Hamilton in a ML year (half inside the park probably
) are crazy. Odds are decent that Hamilton never ever becomes a MLB everyday player. A tool that far off the charts is just so hard to project.
