Playing in the Rising Stars Challenge certainly isn’t a make-or-break deal or even an accurate reflection of a player’s rookie year. But it is an opportunity for Culver to be around the best players in the league that should only help his confidence. “I think that he’s very deserving of that,” Timberwolves coach Ryan Saunders said Tuesday. “You look around the league and Jarrett, the way he’s come on and the way he’s progressed, his improvement and development is a great story over this last month here. . . Being around other players like that, being around other All-Stars . . . that will really help Jarrett.”
