i'll look around for it -- though it seems disingenuous to suggest (if this was the suggestion) that the suit is the only difference between Spitz and Beiderman, since Spitz was swimming in an Olympic final and Beiderman was swimming for the CBC cameras. i assume they were talking about the 200 free? Spitz swam a 1:52 to win gold, and Beiderman swam 1:45 to come in 6th last night. there's no way a suit alone makes 7 seconds difference over a race that lasts under 2 minutes.
for an interesting comparison on how swimming has evolved, check out these two women's relay races, one from 1976 and the other from 2012. note especially starts, turns, how the entire body is engaged, hips to core, in the stroke, whereas in the 70s it was about turnover, cupped hands, etc.
don't know what to say about the doping, though it was very satisfying to watch Lilly King beat Efimova last night. it really comes down to FINA growing a pair and actually cracking down on countries like Russia and China, especially Russia. it's galling that Efimova was even at the Olympics (she trains in Los Angeles yet still got the same drugs as the other Russian athletes).
all countries have dopers, but most countries don't dope the way we know Russia does and the way it's likely China does (although one guesses it's systemic at the regional level).
Hosszu is becoming the story of the Olympics, and to many she's a reminder of Michelle Smith from 1996, right down to the husband-coach.
this was published last year (Hosszu is suing):
Is It Fair To Suspect That Katinka Hosszu's Performances Are Being Aided?
and this article is concerning. i know NBC has caught some flak for sexism by crediting her husband, but given the relationship as sketched out here, it seems inarguable that something not-quite-right is going on.
