Lions DT Tyrunn Walker is expected to get the first crack at the starting job next to Haloti Ngata.
After losing both Ndamukong Suh and Nick Fairley and choosing not to re-sign C.J. Mosley, the Lions acquired Ngata and Walker before spending a fourth-round pick on Gabe Wright at defensive tackle. Walker was a role player for the Saints, but flashed in limited snaps. The Lions are banking on Walker and second-year DT Caraun Reid to take steps forward on the interior.
