Dolphins RB Lamar Miller caught up in depth chart

Miami Dolphins rooking running back Lamar Miller was inactive against the Seattle Seahawks last weekend, as the team decided to dress four other running backs. Miami head coach Joe Philbin said Wednesday that the decision was not "necessarily an indictment of [Miller] or what he did or didn't do."

Miller's role is not quite as defined as some of the other backs on the team, which may be what is preventing him from getting additional playing time. Reggie Bush handles the bulk of the carries as the starter, Marcus Thigpen returns kicks and Daniel Thomas has been the secondary option behind Bush.

Miller has 27 carries for 145 yards and a touchdown this season; he has not had more than three carries in a single game since Sept. 30 -- and just a total of four carries since then.

The Miami Dolphins host the New England Patriots in a big AFC East matchup this Sunday.
