While we do not know when or who it will be, it is very clear that the Chicago Bears are going to draft a running back. The team has kicked the tires and met with draft prospects of all shapes, sizes, and styles of running. They are looking for the perfect back.
In fact, it was reported after the combine that they pretty much were searching for a perfect back.
The back they are looking for needed three-down ability, lateral cuts at the second and third level, and a passing game option, not a check down player.
