After acquiring Kiko Alonso and Byron Maxwell from Philadelphia (pending physicals), restructuring the deals of Ndamukong Suh, Koa Misi and Jordan Cameron and reportedly parting ways with Brent Grimes, Miami appears on the brink of making another big splash.

Williams visited the Dolphins facility over the weekend but left without signing a deal.
