yes with Brunelleschi's lead (but he still needs a big team), but since Buffet only outperforms by about 15% I wouldn't call that "dramatic" in the context of your post. As for Jordan, I suspect five of me could beat one Michael Jordon, and I suck at basketball.
Maybe you could better make your point by avoiding analogies and staying within our hackery field for alpha examples. For example, a single Linus Torvalds in a weekend could put together git, which could then keep thousands of mediocre programmers confused for years :-)
