Michigan’s Dusty May has enjoyed the close bond he’s developed with Saint Louis’ Josh Schertz. The coaches have exchanged everything from philosophies to practice notes to playbooks. But their collaborative relationship is on hold for now as Michigan prepares to face Saint Louis in the second round of the NCAA Tournament. The teams meet Saturday in Buffalo, New York, with a Sweet 16 berth on the line. The coaches became friends when May was at Florida Atlantic and Schertz was coaching Division II Lincoln Memorial. Schertz says he thinks Michigan is the best team in the country.
