The Pistons have still been trying to trade All-Star Andre Drummond but, according to a league source, the Knicks were not engaging as recently as last week. The Pistons, according to a source, are looking for a return of expiring contracts and a young prospect or draft asset. In other words, they’re ready for a rebuild. Although Drummond is an All-Star caliber player, the big issue is he’ll become an unrestricted free agent after the season and a rental doesn’t make sense this season.
