The Miami Dolphins fired Mike McDaniel to hire Jeff Hafley, the Green Bay Packers’ defensive coordinator for the last two years. As Brady puts together his staff, he is losing defensive coordinator Bobby Babich to the Packers, per NFL insider Tom Pelissero. The Packers’ losing Hafley to the Dolphins led to their hiring former Arizona Cardinals head coach Jonathan Gannon as the new defensive coordinator. Denver Broncos defensive pass coordinator Jim Leonhard is reportedly the favorite to be the Bills’ new defensive coordinator, per ESPN’s Adam Schefter. Now he will join the Packers staff under their new defensive coordinator.
