text: The 2023-24 season would be one to remember. Three pivotal graduate transfers, Marcus Domask, Quincy Guerrier, and Justin Harmon joined the team, with Domask and Guerrier starting most games. The Illini went on an undefeated trip to Spain and then beat #1 ranked Kansas in a televised exhibition game. The team lost only two games to non-NCAA tournament teams, once to Penn State and once to Maryland. After finishing second in the Big Ten standings, the team ultimately won the Big Ten Tournament, prevailing over Wisconsin. The team was selected to the NCAA tournament as the #3 seed in the East region. For the first time in Underwood's tenure, the team made the Sweet Sixteen, where it beat the #2 seed, Iowa State. For the first time since the 2004–05 season, the team made the Elite Eight, where it lost to #1-overall UConn.
