The Dolphins added defensive end Mario Williams, cornerback Byron Maxwell, linebacker Kiko Alonso, safety Isa Abdul-Quddus and tackle Jermon Bushrod, among others. Tannenbaum jettisoned corner Brent Grimes and watched defensive end Olivier Vernon, running back Lamar Miller, defensive end Derrick Shelby and receiver Rishard Matthews depart in free agency.
With coach Adam Gase on board, Tannenbaum has the leadership in place that he believes can coax the talent out of the roster.
"We feel like we are definitely making progress here," he said, via the South Florida Sun Sentinel. "We are excited about the things that we've done."
