As Florida Panthers general manager Bill Zito walked up to the podium Saturday at FLA Live Arena, he apologized to reporters for being late. “I don’t even know what time it is,” he said. It was just before 5 p.m., 90 minutes after he was scheduled to speak and five hours after NHL free agency opened. This, in a sense, was a time for him to catch his breath after the previous five-plus hours had truly been that crazy.
