The Los Angeles Clippers lost the most successful coach by winning percentage in the franchise’s history when they dismissed Vinny Del Negro, whose contract was due to expire June 30. Del Negro compiled a 128-102 record during his three seasons with the Clippers and for the better part of the past 14 months, had a strong case for a long-term extension, at least ostensibly. The Clippers beat the Grizzlies in the first round of the 2012 playoffs, then finished with a club-record 56 wins this season. No locker room outside of Bexar County, Texas, is perfect, and there were certainly frictional elements in the Clippers’ camp, but the overall culture was decent.
Del Negro was confident in what he was building, and turned down a one-year extension from the team last October. Yet despite the regular-season success, Del Negro could never shake the perception that he lacked the tactical feel for the game required to become an NBA championship-level head coach. Del Negro’s biggest fans during his five-year career have been owners, Jerry Reinsdorf in Chicago and Donald T. Sterling in Los Angeles. Basketball operations people have always been more skeptical of him.
