By Abraham Gutierrez A pair of 4-7 teams fighting for their playoff lives will lock horns Sunday afternoon at Sun Life Stadium when the Baltimore Ravens pay a visit to the Miami Dolphins in Week 13. Despite coming in as the team that’s expected to lose, it’s no secret that the visiting Ravens – winners of two straight games – will have momentum on their side versus a Fins team that’s lost two in a row entering play. Having that said, one predicts that the most recent changes to the coaching staff will help Dan Campbell improve his record to 4-4 as Dolphins head coach.
