he U.S. Supreme Court recently granted a writ of certiorari and will review American Needle in its 2009-2010 Term.

American Needle offers the Supreme Court an opportunity to settle a longstanding source of confusion: how should antitrust law regulate the peculiar, perhaps incomparable, business entity known as a professional sports league? The stakes could not be higher.
