Dolphins RBs coach Eric Studesville said the team isn't ready to name a starting running back.
"We don’t know that yet," he said. "I think that's going to play out over time." Kenyan Drake would seem to be the favorite for lead ball-carrier duties, though Armando Salguero of the Miami Herald suggested veteran Frank Gore could see a bigger workload than expected. Salguero also said the Dolphins "really like" fourth-round power back Kalen Ballage. Miami's backfield roles will likely be determined during training camp.
