I don't expect the Lions to be aggressive in signing big time free agents. That doesn't seem to be their philosophy. Build through the draft and supplement through free agency. I would sign someone like Stephon Gillmore. He's old but still producing. One year contract while you draft and develop a young corner. I would even bring back Moseley. Non guaranteed contract and bring him to training camp and see if he can earn a spot. CJGJ, Branch and Melifonwu are all redundant. I probably wouldn't bring back CJGJ unless he comes on a cheap prove it deal. The Lions can save at least $5 million in cap space if they cut Walker so I think he's gone. Your starting safeties would be Melifonwu and Joseph with Branch as the hybrid.
