University of Illinois men’s basketball head coach Brad Underwood says he’s “surprised” by the arrest of four NCAA assistant coaches by the FBI this week.

Oklahoma State coach Brad Underwood is leaving Stillwater for Illinois after just one season, calling the chance to lead the Fighting Illini a "once in a lifetime opportunity." Underwood spent three successful seasons at Stephen F. Austin before signing on to coach Oklahoma State for 2016-17. "We were looking for a proven winner who would build upon our proud tradition while developing an unmistakable identity for Illinois basketball," Illinois athletic director Josh Whitman said in a statement. "Brad's teams play a fast, aggressive style and show unyielding toughness."
