Dolphins tap Hafley to lead hard-nosed rebuild after Packers stint

The Miami Dolphins hired Green Bay defensive coordinator Jeff Hafley as their next head coach on a five-year deal, signaling an identity shift toward a tougher, defense-focused approach under new GM Jon-Eric Sullivan. Hafley helped the Packers’ defense rank well in his first two seasons, but injuries and other factors affected 2025. The team now faces questions at quarterback and offensive play-calling, with Tua Tagovailoa’s future and potential QB changes looming as they try to close the gap with the Patriots and Bills.
