Chauncey BillupsÂ isn’t worried about hisÂ Denver NuggetsÂ not picking up any big-name players this offseason. But he is worried about a teammate who hasn’t exactly been helping his name lately. With that in mind, Billups will fly Sunday to Las Vegas, where embattled guard JR Smith has relocated. Billups will spent the final three weeks of August working out with and mentoring Smith. “We’ve got some talking to do,” Billups said in an interview with HoopsHype.com. Smith last month spent 24 days in jail after pleading guilty to reckless driving in connection with a 2007 automobile accident in which a friend, Andre Bell, died.
