- The most significant question facing the Pistons heading into training camp will be how to use Isaiah Stewart , who’s entering the first season of a four-year, $60MM extension, says Keith Langlois of NBA.com . Langlois notes that Stewart played primarily at power forward last season, but Detroit has limited options on its front line, so Stewart may be the primary backup to center Jalen Duren even if he’s in the starting lineup. Simone Fontecchio and newly signed Tobias Harris are both capable of being stretch fours in smaller lineups, Langlois adds.
