Ogbah, the Cleveland Browns' 32nd overall pick in 2016, has racked up 18 sacks in 50 career games across four campaigns. The 26-year-old spent last season with the Kansas City Chiefs.
The Dolphins have been big spenders so far this offseason, specifically on defense. They've already added cornerback Byron Jones on a record-setting deal, former New England Patriots linebacker Kyle Van Noy, and ex-Buffalo Bills defensive end Shaq Lawson.
Miami finished last in the league in sacks, pressures, and pressure rate last season.
