Alex Marvez of the Sporting News mentions that there has been speculation going around in league circles the past week that Patriots defensive coordinator Matt Patricia could be headed to the Lions as a replacement to Jim Caldwell. According to Marvez, Caldwell is not the only member of the Lions who could be gone in 2018, given that VP of player personnel Kyle O’Brien is emerging as potential GM candidate. Patricia was linked to the Lions last year before Detroit elected to retain Caldwell and sign him to a one-year extension.
