A couple may come back but at the moment I think it is zero.
Don't take my word for it as I am too lazy to look it up.
Adam Miller, Justice Williams, and Mwani Wilkinson will all be returning. Miller started on the 2021 Illini team, but was injured for the entirety of the 2022 season. He figures to be a starter. McMahon is also bringing over 3 of the top 4 scorers from Murray State, a team that won 31 games and made the round of 32.
LSU is also bringing in Cam Hayes (NC State) and Derek Fountain (Miss State), who I think both have a fair amount of potential. They both regressed a bit last season, but they could be important pieces to LSU's success. And McMahon also signed two highly regarded recruits, one of them being Tyrell Ward, who is pegged as the #23 player in his class by rivals. This team is going to be fine. Borderline top 25 team in the preseason, IMO.
