The Dolphins still are looking to upgrade the offensive line and signing Randall certainly would be ironic considering the lost his job as the Texans' starting right tackle this offseason when Todd Wade signed with Houston.
As for Edwards, he's a former starter for the Packers who would come in and compete with Arturo Freeman for the starting free safety spot. It's clear by now the Dolphins have their reservations about Freeman, which is why they want to add a starting-caliber safety, whether it be in free agency or through the draft.
