Four years ago, Ndamukong Suh was the hottest free agent in football. Before teams were even allowed to make offers, let alone finalize them, there were reports that he was going to leave Detroit for Miami and sign the richest contract for a defensive player in the NFL, and that's what happened. Suh is a free agent again this year, but it's been a quiet free agency: There hasn't even been a report that he's talking to anyone.
