The Miami Dolphins traded up in the fourth round to draft Miami running back, Lamar Miller.

The only problem is, the Dolphins have Reggie Bush, who was great last season, and Daniel Thomas, who they drafted in the second round in 2011.

So what will Miller's role be for the Dolphins?

The Dolphins have made it clear they would like to start Miller out as a possible kick returner. It would be ideal for Miller to be involved as a receiver in the future, but he barely did much receiving in college and likely has to improve in that area first.

They are going to have to find a way to get Miller and his 4.4 speed the ball, whether it's from a handoff or not.

I think Joe Philbin looks at Miller as a shiny, new West Coast Offense weapon, but for now, he won't be heavily involved in the running game. Best case scenario for Miller is using him in certain situations where the Dolphins are looking for a big play. He needs time to develop before he is out there consistently. Maybe by the end of the year, the coaching staff will feel comfortable with his ability to run in between the tackles and catch the ball.

Picking up Lamar Miller was a huge value in my opinion, and Ireland couldn't even resist by trading up to get him. Miller was projected to go much higher on many boards, and clearly the Dolphins thought so too. Even with running back not be a glaring need, the pick was of great value and the Dolphins added another fantastic football player to their team.

Miller also provides insurance in case Reggie Bush decides to walk after this season. If Bush leaves, the Dolphins still have a speed back on their roster. Hopefully Miller would be ready by then to handle a good amount of carries. And hey, you never know who the next game-breaking rookie will be. Look at what Demarco Murray did for the Cowboys.

There is no chance Miller beats out Reggie Bush or Daniel Thomas for the top spot, but as injuries occur, and the season gets late, Miller will see some carries. The Dolphins have set themselves up nicely for a bight future on offense. They drafted Tannehill, Miller, and Michael Egnew.

With these players drafted in the same season, it allows them to develop and build chemistry together for years and years. When you throw in the sleeper potential of the late-round receivers, you can't help but be happy with future of the offense.
