In his 20-minute speech during Monday's ceremony, Jackson did not specifically say UND should do away with the nickname, but he asked officials to ponder what could be gained by keeping it.
Jackson said he had been asked by his Lakota friends to speak out against the nickname. He said UND has a chance to embrace change.
Under a settlement reached last fall with the NCAA, UND has three years to win the approval of North Dakota's Sioux tribes if it wants to continue using the name without sanctions. The NCAA considers the name hostile and abusive, but school officials dispute that.
North Dakota competes against the University of Wisconsin in men's and women's hockey. UW has a policy that prohibits its sports teams from scheduling teams with Indian nicknames, but makes an exception for opponents within conferences in which the Badgers compete.
