A divorce between Lamar Miller and the Miami Dolphins has been coming for some time. The Dolphins do not know how to fully utilize Miller's skill set and he has been chasing carries all season long.
The weeks he does carry the ball behind a very porous Miami Dolphins offensive line he puts up some solid numbers but after drafting Jay Ajayi last season the Dolphins runner might think that this backfield has suddenly become too crowded. The Cowboys could use a somewhat experienced NFL running back to back up Darren McFadden or start over him all together.
McFadden was the fourth best rusher in the league but when you consider his injury history and age it would most likely benefit the team to find a reliable and suitable backup. Not only is Miller an excellent runner in a zone scheme he is only 24 which means he should have 5 more years left before declining. Miller should command a contract similar to what DeMarco Murray had before he left the Cowboys, somewhere in the 5-6 million range.
The Cowboys may want to sign Miller but may also want to draft a young running back coming out of college in the later rounds if you factor in what happened to Lance Dunbar. Coming off of such a serious injury it would be wise to find to players you would be comfortable with having to carry load for this offense.
