Over the last several years the Miami Dolphins have found plenty of success with mid-round runners. Unlike the 2nd round selection of Daniel Thomas, which they traded up for, the 4th and 5th rounds have provided far better outcomes.
Since that 2011 draft bust featuring a failed trade up for Thomas, the Dolphins have found more production even with the trades.
In 2012 the Dolphins took Lamar Miller in the 4th round. Miller had a very good career with the Dolphins and many fans were surprised that the Dolphins opted to let him leave via free agency rather than re-sign him when his rookie contract was up.
