In a surprising move, the Bulls will not renew the contract of lead assistant coach Ron Adams.

Adams, in his second stint with the Bulls, came to Chicago following a successful run as Scott Brooks’ lead assistant in Oklahoma City. A longtime friend of Tom Thibodeau’s, Adams left the Thunder to be closer to his family, who remained in the Chicago area for school reasons following Adams’ first stint with the Bulls under Scott Skiles.

According to sources, general manager Gar Forman made the decision, not Thibodeau. Forman informed Adams on Friday.
