Miami's running back depth chart was so barren last season that quarterback Ryan Fitzpatrick led the team in rushing with a mere 243 yards. The Dolphins filled that hole on their roster on Saturday, trading for San Francisco's Matt Breida in exchange for a fifth-round pick.
Breida has struggled with consistency in his career, falling outside the top 20 in rushing DVOA in either of the past two seasons. But he is undeniably explosive -- among active running backs with at least 300 carries, only Nick Chubb and Aaron Jones have averaged more yards per carry.
