​Greg Powers, head coach of Arizona State University’s hockey team, addressed members of the media for the first time since Matthew Mayich collapsed during a team workout more than a month ago.Powers said Mayich, 21, remained hospitalized but declined to say whether he held himself responsible for what happened. Mayich has zero chance of recovery, according to a lawyer representing his family.Powers faced questions about the workout at a Sept. 23 National Collegiate Hockey Conference media day session, his first public media appearance since Mayich’s collapse.Powers’ appearance came a day after the university released a preliminary report showing hockey coaches failed to follow the university’s heat guidelines and policies for vetting an ex-Green Beret guest trainer involved in the near-fatal outdoor workout. The report did not identify anyone responsible for the failures surrounding the workout.Here’s what happened at the news conference, what Powers declined to discuss and what one player said about Mayich’s hospitalization.What happened at ASU hockey media day Sept. 23?Powers appeared alongside ASU forward Ben Muthersbaugh, who took questions first.
