It has been eight years since the Pistons won an NBA title, and the lone player left from that team is Tayshaun Prince. Ben Wallace is gone. So are Rasheed Wallace, Chauncey Billups, Richard Hamilton, Corliss Williamson, Mike James, Lindsey Hunter and coach Larry Brown, among others. Prince could have left but signed a contract last season. Now the elder statesman, Prince, 32, is surrounded by good, young talent. “I use this time to get in shape, mostly,” Prince said of the time just before the regular season starts. “I think most guys use July, August and September to get in some kind of basketball shape, but once training camp comes, it’s a whole different mind-set as far as being in shape. You just make sure you are at that 75-to-80% level for training camp, and then you start playing two-on-two and three-on-three — a lot of contact stuff — that helps get you in even better shape.
