Gonzaga is moving to the PAC 12. Words are important. The AD could have easily said, "that is not true" or "that is false" or "we're not moving to the PAC 12" or "we are committed to the WCC" if he was denying that Gonzaga is moving to the PAC 12.
He did not. Instead, the AD chose to use words that one would use to leave things wide open.
