The Dolphins are reportedly concerned about Daniel Thomas' ability to be a physical goal-line back.
After two NFL seasons, it's obvious that Thomas is not a difference-making NFL runner. He's averaged just 3.53 yards per carry, scored a mere four touchdowns, fumbled five times and missed seven games due to injury. With Lamar Miller assuming feature back duties, Thomas will simply be trying to carve out any role he can this offseason. If he can't pin down the goal-line job, it's another boost for Miller's rapidly rising fantasy stock.
