The first time Bryan Colangelo had the chance to make the first selection in an NBA draft, he didn’t have to deal away two picks or place any protections on them to do it. This was June 2006, and Colangelo had been the Toronto Raptors’ president and general manager for just four months, and fortune had given him and the franchise a gift. Though the Raptors, at 27-55, had compiled the fifth-worst record in the NBA in 2005-06, they won the draft lottery. They had the same opportunity that the 76ers, in the wake of their recent trade with the Boston Celtics, have Thursday night.
