DES MOINES, Iowa (AP) — Drake assistant coach Mike Gibson has resigned to pursue opportunities outside of basketball. The 29-year-old Gibson has been an assistant with the Bulldogs for four seasons. But Gibson says his priorities have shifted and he’s decided to pursue a job in the business world. Gibson worked with current Drake head coach Mark Phelps at Arizona State from 2006 to 2008 after a one-year stint on coach Tom Izzo’s staff at Michigan State. Drake also says Jamelle McMillan, the director of basketball operations, is leaving the program after one season.
