Vanderbilt won the game, 77-44.

Former Lawrence High basketball player Brad Frederick, who has been an assistant coach the past 14 years at Vanderbilt, will be joining Roy Williams’ North Carolina staff, the website Inside Carolina reported Thursday night.

Vandy announced Frederick’s resignation Thursday morning, and, at the same time, reported the hiring of Harvard’s Yanni Hufnagel as new assistant on Kevin Stallings’ Vandy staff.

A UNC official could not confirm Frederick’s hiring when reached by Inside Carolina on Thursday night.

UNC has been advertising for a director of operations/director of player personnel for men’s basketball. It is unclear whether Joe Holladay, the current director of basketball operations, is remaining on Williams’ staff.

Frederick, the son of former KU athletic director Bob and Margey Frederick of Lawrence, played on the Lions’ 1995 state championship team before walking on at North Carolina, where he played for both Dean Smith and Bill Guthridge.

Frederick, 36, was a member of former KU assistant Stallings’ original Vandy staff.

Frederick had been a candidate for an opening on former KU coach Williams’ UNC staff last year, the position ultimately filled by Hubert Davis.

KU officially has one official opening, most likely two, on Bill Self’s staff. Self has not yet announced a replacement for assistant coach Joe Dooley, who recently accepted the head-coaching post at Florida Gulf Coast. Self has said director of basketball operations Doc Sadler likely would not be back, instead seeking a return to actual on-court coaching as a head coach or full-time assistant. Former Nebraska head coach Sadler has been listed as the leading candidate to join Fred Hoiberg’s Iowa State staff as a full-time assistant.

Chalmers’ dad sued

Former KU director of basketball operations Ronnie Chalmers is being sued by David Sugarman, his former business partner in the SugarTime sports agency, for allegedly stealing property from and illegally competing against their jointly operated sports agency, Ken Berger of CBSsports.com reports. Sugarman seeks nearly $65,000 in damages, plus unspecified punitive damages.

The two operated SugarTime sports agency from Dec. 2012 until April 2013, CBS reports. According to the CBS report, Sugarman alleges Chalmers “did not pay his half of agency expenses and was caught on video surveillance stealing documents and files containing propriety information from the agency’s Miami offices the night before he resigned from the firm.”

Since resigning, Sugarman said he violated a no-compete clause by continuing to recruit potential clients including KU’s Ben McLemore, Travis Releford and Elijah Johnson. Chalmers’ son, Mario, of the Miami Heat is not involved in the lawsuit.
