Antitrust professors amicus in O'Bannon

A group of antitrust professors has filed an amicus brief in the Ninth Circuit appeal in O'Bannon v. NCAA (media coverage here). I know nothing about antitrust. But the gist of the argument appears to be that once the district court found the NCAA had some rational basis for its limits, the antitrust Rule of Reason was satisfied and it was beyond the court's power to order the NCAA to change those limits.
