In 2013 the Dolphins running backs were like the Dolphins as a whole, inconstant. The combination of Daniel Thomas and Lamar Miller combined for the 26th ranked rushing game in the NFL at 90.0 yards a game. These two got no help from the offensive line, but I think Daniel Thomas has to go, Miller is still unproven and I think he can be a good NFL running back.
Daniel Thomas had only 5 good games according to pro football focus. Not 5 good games in 2013 either, five in his entire career. He was on the roster because he was a good pass pro running back aswell…. He didn’t have one good game in pass pro, according to PFF. In his career he has only two 100 yard rushing games, he has twice that many averaging one yard or less in a game. He has averaged 3.6 yards a carry for his career, I think it is time for the Dolphins to move on.
Lamar Miller has shown enough upside to where I think he can be a good running back in the NFL. Part of the reasoning behind his struggles is because he had to share carries with Thomas, poor play calling doesn’t help either.
Miller averaged 4 yards a carry in 2013 with two touchdowns. When he got 10+ carries he averaged 60 yards a game and 3.8 yards a carry (this includes a game with an average of 0.3 and 0.8 yards a carry) . When he carried the ball less than ten carries a game he averaged 24 yards a game with an average of 3.6 yards a carry.
According to PFF he had more good games than Daniel Thomas and even was better in pass protection. His pass catching needs work though as he finished the season with a -0.5 grade. Miller should get the starting job at running back in 2014, the Dolphins should also sign someone.
Donald Brown and James Starks are two names that pop out at me as good fits for the Dolphins. They would both be relatively cheap and would be experienced back ups. It would also be wise for the Dolphins to sign a real fullback. Some teams can survive without one, if the Dolphins want to run the ball in 14 I think a football is a must.
