It looks like the market for free agent RB Dalvin Cook is heating up. According to Barry Jackson of the Miami Herald, the Dolphins have made a formal contract offer to the veteran back. Jackson went on to say that “there's mutual interest" and that Cook "has called Miami a 'perfect fit'.” NFL Network's Tom Pelissero also recently spoke about Cook on The Rich Eisen Show, stating that the veteran has received "multiple offers" from various teams, so the Fins will not be alone in their pursuit. Cook showed some signs of decline last season, averaging his fewest rushing yards per game (69.0) since 2017 and losing significant target share. Wherever he ends up, we're probably not talking about a slam-dunk RB1 in fantasy anymore. But he should have a role worthy of mid-round draft consideration. Cook landing in Miami would throw an already busy backfield -- Jeff Wilson Jr., Raheem Mostert, and 2023 rookie De'Von Achane -- into an absolute frenzy. Keep an eye out for further updates.
