Tony Terraciano used to be a part of the main cast on Blue Bloods, playing Jack Reagan, but from season 10 onward, his role got smaller and smaller. The 14 seasons of Blue Bloods follow the lives of the Reagans, an Irish Catholic family living in New York City who have a proud lineage of working in law enforcement. Though Blue Bloods was canceled, much to many fans’ dismay, the series remains an engaging and thrilling police procedural with an excellent cast at the center of it.
