Joe Mantegna has been hired to replace Mandy Patinkin on Criminal Minds. He will appear in the sixth episode playing Agent David Ross. Ross will be a complete opposite to Gideon. He was an orignal member of the BAU who comes out of retirement for mysterious reasons. Uncomfortable with private jets, high tech stuff and female agents. Patinkin returns on October 3rd to wrap up the Gideon role. Any thoughts on Mantegna joining the show?
