Any advantages gained are outweighed by the disability.
Then I reckon the US Olympic Rowing team outta fit one of their boats up with an Evenrude and about 2 dozen pontoons, because clearly... SOB is in NO shape to participate under the current draconian conditions.

"Disabled golfer Casey Martin may use a cart to ride in tournaments, the Supreme Court ruled Tuesday, saying
federal law requires a leveling of the playing field for the handicapped, even in pro sports."
I mean... not to be calous about this man's condition... it's unfortunate, yeah... but we're talking about professional athletes playing at the top of their respective fields. Do we really want to see this door being openned?
Btw, what is the definition of "handicapped", anyway? Is it something you're born with? A disease? Or could it also include the numerous career ending injuries professional athletes are constantly aflicted with?
If some kind of heriditary disease only... Could hemopheliacs who have ambitions on the NFL be given flags in lieu of getting tackled?
If it includes just pure debilitating injury, could a goalie with a bum knee have the posts moved in to offset his restricted movement?
Extreme cases, granted... but it's interesting. I'm not sure how and where the line would be drawn.
