It continues to worry me that we would delete an article on any Olympian.
Oh so we're now a directory of losing athletes as well are we?
This is getting a little off topic, but I'll contribute anyway. Anyone that qualifies for the olympics is notable for that reason alone. The problem with this particular case is that he didn't qualify, he got in on a wildcard. Basically, he reached the olympics by luck - you can't be notable simply by being lucky. However, it is a fairly unique case and got lots of press coverage, so it's notable for that reason even if he isn't notable for simply being an Olympian.
A similar situation - a Formula One racing driver that is always at the back of the field. He's not notable within F1, but he's very notable within racing in general, as he's reached the top competition. Reaching F1 (and similarly the olympics) is a major achievement, even if you lose.
