The Dolphins signed WR Mohamed Sanu to a 1-year deal. Sanu turns 33 next month, but he’s likely getting a look partly because of his familiarity with HC Mike McDaniel. (They spent 2021 together in San Francisco.) Of course, Sanu’s play has fallen off a cliff, with the veteran notching just 32 catches over the past 2 seasons. He's a roster long-shot.
