Dolphins RB Lamar Miller will be the starter this season, but Daniel Thomas has been practicing well and will likely be the goal-line and third-down back. Miller said he wants to be an every-down back, and offensive coordinator Mike Sherman said recently that he could see Miller as a three-down guy. But Thomas is better in pass protection and is holding onto the ball in practice — fumbling was an issue for him in his first two seasons.
Fantasy Impact:
If Thomas does play on third downs and is the goal line back, it will put a significant dent in Miller's upside.
