There has only been one NBA unicorn: Robert Archibald, a 2nd round pick for Memphis in the 2002 draft. A 6'11" center out of U of Illinois, he scored 52 points in his 2 NBA seasons.

Why is he the only unicorn?

The official national animal of Scotland is the unicorn.

Exactly one Scot has ever played in the NBA.

Robert Archibald, born in Paisley, March 29, 1980.
