Prior to the 2011–12 season, Illinois welcomed seven new players into the program. The 2011 recruiting class was ranked No. 13 by Scout.com and No. 11 by both Rivals.com and ESPNU. The class was celebrated for its talent and depth, and is the second class in a row that has revived top-15 national rankings. Six true freshman; Tracy Abrams, Myke Henry, Devin Langford, Nnanna Egwu, Mike Shaw, and Ibby Djimde as well as one transfer senior, Sam Maniscalco joined the 2011–12 team. Maniscalso transferred from Bradley University after graduating in May 2011. Because Bradley did not offer the graduate program he enrolled in at Illinois, Maniscalco was eligible to play immediately.

With stops in Rome, Florence, Venice, and Como the trip was a combination of basketball, sightseeing, and team-building. The team played four full games, which included wins over Roma Select, Castellanza Select, and Fulgor Omegna as well as an overtime loss to the New Zealand National team Also, the Illini traveled to Aviano Air Base, where Illinois played West Virginia in a 20-minute scrimmage and the Aviano varsity team in a 10-minute scrimmage.
