Terry Lanni didn't take a victory lap. He didn't stop for the applause and he didn't wait for the accolades. Instead, Lanni told the world on Nov. 13 he was retiring as chairman and chief executive officer of gaming industry giant MGM Mirage after 13 years at the helm. Five days later, the casino company's board of directors voted to have President and Chief Operating Officer Jim Murren fill Lanni's positions.
