Shortly after firing George Karl, the Denver Nuggets offered the Boston Celtics a first-round draft pick as compensation to pry coach Doc Rivers out of his contract, league sources told Yahoo! Sports. Nuggets CEO Josh Kroenke made a bid for Rivers approximately 10 days ago, informing general manager Danny Ainge of his willingness to part with a pick if the Nuggets were able to procure Rivers. Nevertheless, Boston wasn't prepared to start the process of letting Rivers leave, and discussions never went beyond one brief conversation between Kroenke and Ainge, league sources said. Denver quickly moved onto its current two finalists for the job: Lionel Hollins and Brian Shaw. Both candidates made strong impressions on Kroenke and new Denver GM Tim Connelly in interviews this week, sources said. The Celtics are haggling with the Los Angeles Clippers over possible compensation for Rivers, with whom Los Angeles has negotiated a long-term deal, pending an agreement with Boston. The Clippers want Boston to release Rivers without compensation, freeing the Celtics of the three years and $21 million left on his deal, sources said.
