Assistant coach Charles Oakley’s health concerns could force him to quit his job, so the Charlotte Bobcats have hired another coach just in case. From the AP: “The Charlotte Bobcats added an assistant coach for next season on Tuesday amid concerns Charles Oakley won’t be able to return to the bench because of health issues. Coach Paul Silas announced former Golden State assistant Rob Werdann will join his staff. The former St. John’s big man who played briefly in the NBA has also been an assistant in New Orleans. ‘I was told they were going to add a coach and I jumped at the chance,’ Werdann said. Oakley missed the final 13 games last season with a back problem he claims was caused when he was assaulted at a Las Vegas resort in May 2010. Oakley has sued the resort and said earlier this month he’s contemplating surgery. Silas says he still hopes Oakley returns, but needed to make sure he had at least three assistants next season. ‘If he was here now, we probably wouldn’t have been looking at anyone else,’ Silas said of Oakley. ‘But since he’s going to have an operation soon and that kind of thing, we had to bring somebody else in.’”
