Previous season
The Knights finished the 2022–23 season 17–14, 10–6 in NEC play to finish in a tie for second place. As the number two seed in the NEC tournament, they defeated St. Francis Brooklyn and Saint Francis (PA) to advance to the championship game where they lost to Merrimack. However, because Merrimack was in a transition period from Division II to Division I and ineligible for the NCAA Tournament, the Knights received the conference's automatic bid to the NCAA Tournament as the No. 16 seed in the East region. In the First Four, they defeated Texas Southern to advance to the First Round. There they became only the second No. 16 seed ever to upset a No. 1 seed by defeating Purdue. The Knights would then go on to lose in the Second Round to Florida Atlantic.

On March 21, 2023, head coach Tobin Anderson left the school to become the head coach at Iona. The same day, the school promoted assistant coach Jack Castleberry to head coach.
