The AP reports: Tayshaun Prince’s post-Olympic slump might finally be over. Prince, averaging just seven points on 31 percent shooting, scored 17 points in 29 minutes Wednesday night, and the Pistons beat the Cleveland Cavaliers 97-79. The Cavaliers were playing without LeBron James, who was in uniform but took a planned night off… The Pistons were led in scoring by Rodney Stuckey’s 20, but the defense-oriented Curry wasn’t completely happy with his second-year guard’s performance… Daniel Gibson led the James-less Cavs with 16 points and Mo Williams scored 14 in the first half. Cleveland finishes its preseason schedule Friday against Washington.
