The Miami Dolphins want Lamar Miller to be a more physical running back in 2014.
The Dolphins were disappointed by the production of Miller and Daniel Thomas last season.
"They're a good complement to each other, and we like Miller's speed and explosiveness," one Dolphins staffer said. "Miller has the higher ceiling, but you wish he ran with a more physical (style). And both have to improve as blockers."
Miller was one of the NFL's least elusive running backs last season.
