NFL Nation reporters break down the opening day of free agency for all 32 teams:
AFC EAST
Buffalo Bills: The Bills were quiet Wednesday and aren't expected to be active for the rest of the week. They have only about $4.5 million in cap space, the result of both their big spending last offseason and their ability to get their top free agents -- defensive tackle Marcell Dareus and offensive linemen Cordy Glenn and Richie Incognito -- under contract prior to Wednesday. -- Mike Rodak
Miami Dolphins: The Dolphins officially completed their blockbuster trade with the Eagles on Day 1 of free agency.
