During the 2005–06 season, the Hawkeyes went undefeated at Carver-Hawkeye Arena for the first time in school history and finished in a second-place tie with Illinois with an 11–5 conference record, one game behind Ohio State. However, the Hawkeyes defeated Minnesota, Michigan State, and Ohio State to win the Big Ten Tournament and finish 25–8 going into its third NCAA Tournament under Alford. They were ranked No. 11 nationally and seeded #3 in the Atlanta Regional of the 2006 NCAA Tournament, but lost in a first-round upset to #14 seed Northwestern State 64–63, leaving Alford with only one NCAA Tournament win since taking over at Iowa. The game was lost on a last-second shot, and the Hawkeyes would not return to the Round of 64 in the NCAA Tournament until 2014–15.
