The Detroit Lions are revving up their pursuit of safety help, hosting Thomas DeCoud and Chris Clemons on free agent visits, and they added more depth to their defensive line. DeCoud already finished his visit and said he left town without a contract offer. It was his first visit since the Atlanta Falcons released him in a cost-cutting move earlier this month. Clemons, who played the last five seasons for the Miami Dolphins, is visiting today. “Just came in for a visit just to check it out,” DeCoud said. “Got to meet all the coaches and stuff and got to make a decision. “It went really well. Being a (defensive back), you can’t argue with being able to play behind a front seven like you guys have.” DeCoud, who turned 29 on Wednesday, made the Pro Bowl after a six-interception season in 2012. He started all 15 games he played last year and said he also has received interest from the Dallas Cowboys, Oakland Raiders and Baltimore Ravens, though he does not have any other visits set up yet. Clemons was one of the Lions’ top targets at the start of free agency, though coaches wanted to explore adding former Baltimore Ravens safety James Ihedigbo. Ihedigbo visited last week, and the Lions offered him a two-year contract, but he did not have an agent at the time and went home without striking a deal. Ihedigbo has since hired an agent and is considering the Lions and two other teams. The Lions need a starting safety to pair with Glover Quin after releasing Louis Delmas last month. Delmas has since signed with the Dolphins.
