Who doesn't love a good conspiracy theory? Did Michael Phelps really win the 100m Butterfly final? This guy says NO, and he makes a very compelling case.
The New York Times weighs in but their findings are somewhat inconclusive.
Alas, the "fix" appears to be because of the angles of the camera and the light. SI.com's photo sequence appears to show Phelps winning by an unfathomably small margin... but doesn't SI have a vested interest in Phelps breaking the record for most golds in an Olympics? [What's that sound? Is that what I think it is??]
