With the departure of Reggie Bush via free agency, the Dolphins added some much needed depth to the running back position. Gillislee is extremely talented and has huge upside but lacks the fundamentals to be an every down back. His biggest problem is not his blocking, but more his inability to grasp the concept of ball security, which could keep him off the field for the majority of 2013. Lamar Miller seems to be the clear-cut No.1 for 2013, but because of his talent, and lack of other options, Mike Gillislee is someone to keep an eye on for next year. He could be an asset if he overtakes Miller as the lead back, or as the third down pass-catching option, where Daniel Thomas wouldn't be a threat to his playing time.
