Since the days of Karlos Dansby — and probably even further back, Hall of Fame linebacker Zach Thomas — the Dolphins have been searching for the perfect linebacker to anchor the middle of Miami’s defense. I admittedly thought Raekwon McMillan could be that guy. And I probably felt similar about 2022 third-round pick Channing Tindall, too. But this time, I really do believe the Dolphins found everything they’ve hoped for in a middle linebacker — when they signed former Tennessee Titans David Long Jr. to a two-year deal worth $11 million earlier this offseason.
