Robert Louis Hansen II (born January 18, 1961) is an American former professional basketball player.

As a senior, he averaged 26 points and eleven rebounds per game to lead his team to an Iowa Class 4-A boys' basketball championship in 1979.

His success in high school made him a prized recruit for head coach Lute Olson and the Iowa Hawkeyes, where Hansen played a key role on the team that reached the 1980 Final Four.

Head coach Phil Jackson decided to pull Jordan from the game in favor of Hansen,[9] hoping for an extra jolt to start what looked to be the final corner of a Finals looking to require seven games to determine a champion.

According to longtime Bulls writer Sam Smith, Jackson may have wanted to rest his starters considering no team had ever come back from a 15-point deficit to win an NBA championship,[10] and Hansen started the fourth quarter with a three-pointer, his only field goal of the game, and a steal off Jerome Kersey.

[9] Scottie Pippen led a 14–2 Bulls rally,[11] and, along with Hansen and fellow reserve big man Stacey King, helped the Bulls get within three points by the time Jordan was put back in the game to replace Hansen.

The Bulls completed the comeback, eventually rallying for a 97–93 victory and winning their second consecutive NBA championship.
