Caldwell likely will have the most direct contact with Rosen as his quarterbacks coach -- and it will be a luxury for an inquisitive mind like Rosen to get plenty of one-on-one attention with the man who coached Peyton Manning for a decade. Caldwell also has been a two-time NFL head coach, and he's the most veteran coach on the Dolphins' staff -- a perfect brain for Rosen to pick.
Expect the Dolphins' offense under O'Shea, Caldwell and running backs coach Eric Studesville to include heavy usage for running backs in the passing game, quick easy-read passes, a middle-of-the-field attack, and play-action to keep defenders guessing.
