Pruitt last night said he believes the time he has spent the past few weeks playing against other draft-eligible players will make him a better college center.
N-B-A teams have reportedly shown only limited interest in Pruitt.
The 6-foot-10, 245-pounder said in April that he would try his luck in the N-B-A draft, but he didn't hire an agent. That allows him to return to the Illini.
Pruitt, who is from Aurora, started 35 games last season. He averaged better than eleven points a game, second best on the team.
The Illini were 23-and-12 and went to the N-C-A-A Tournament, where they lost to Virginia Tech.
